除了《纪念碑谷》,这款向视错觉大师埃舍尔致敬的游戏,再次演绎了视错觉的精彩 - 知乎首发于最美应用 | 有价值的好应用切换模式写文章登录/注册除了《纪念碑谷》,这款向视错觉大师埃舍尔致敬的游戏,再次演绎了视错觉的精彩马力在知群2016 年度新知答主相信大家对《纪念碑谷》一定不会陌生,这是一款经典的利用视错觉的游戏,同理还有《无限回廊》,玩过这么多视错觉游戏,那么你们知道视错觉大师埃舍尔么?今天的游戏将再次演绎视错觉的精彩。埃舍尔一直被称之为三维空间图画的鼻祖,可能也是因为他喜爱数学又广泛涉及其他领域,所以他的画才会这么特别。(图为埃舍尔的作品《埃舍尔瀑布》)今天这款游戏【kubic】就是由一群喜爱埃舍尔的游戏设计师们做的,不用说你们也能猜到,游戏利用了空间错觉、几何拼接、悖论结构等视觉原理让一些看似毫无联系的方块拼成了视错觉的三维图形。简单来说就是一个三维拼图游戏。游戏一共60关,每12关为一个颜色,最后的12关被四个颜色平分,更为复杂多变,身为益智解谜游戏,这个游戏并没有卡关的情况,因为你可以选择自己喜欢的关卡玩,随意的选关让游戏的自由度高了不少,玩家不会一门心思的玩一关却因为一直过不去而放弃游戏,这对于玩家来说是一种很好的体验。虽然关卡越来越难,但是灵感也决定了你能否拼成规定图形的关键。游戏随着图案的复杂,干扰项也跟着多了不少,挑取自己有用的部分,叠加多余的方块,仔细分析原图才能找到取胜的关键。游戏中每一个方块摆放的位置和层次稍有变化就会变成凹凸不同的两种感觉的图形,玩家在这过程中很容易迷失在错觉中找不到方向,所以如果你对空间结构没有太好的认知,或者对图形辨别能力差,那么这款游戏对你来说的难度就很大了。这款游戏和《纪念碑谷》的最大不同就是它是把三维的图形拼成二维的,而《纪念碑谷》则是在二维的世界走三维的地图,三维放进二维显然难度更高,这也就加深了这款游戏的可玩性,游戏空灵的背景音乐和干净简洁的画面直接的衬托出三维的方块们,让你心无杂念的游走在错觉的世界里,也是游戏的加分项。就是这么一款三维拼图的游戏,相信能让你在这个夏末有个好心情~——————————————————本文来自极具颜值的最美撰稿人 @情深不寿iPhone & iPad | 69.1 MB | ¥12.00 | iOS 6.0+Android | 40M | $1.99 | 2.3及更高版本下载地址等更多内容请前往 —— kubic喜欢的话就 “赞” 一个吧^^--------------------------------------大家都爱看1. 倾情奉献!我们用 8 天时间整理了 80 余款优秀的摄影应用,给最爱摄影的你~2. 干货|超实用壁纸应用大合集,你想要的壁纸在这里统统都能找到!3. 在陌生城市里,如何像当地人一样地玩耍?下载 最美应用官方客户端编辑于 2016-08-22 11:30iOS 游戏Android 应用赞同 27522 条评论分享喜欢收藏申请转载文章被以下专栏收录最美应用 | 有价值的好应用一起发现好用、好看和好玩的应用

$8.20$
报道日,和 ix35 一起拿着垒球去大厅面基。但由于我 LCT 标记下传写错了调了一会儿下楼晚了,只面到了多头。
然后去 HEZ 寝室打了两把狼人杀(实际上根本不会玩,全程划水),其中有一些同学水平很高,说的话里我有一半听不懂。某次睁眼的时候 he_____he 突然出现,吓了一大跳。
下午打了几个板子,晚上打了很多电动,感觉很爽。
$8.21$
打电动。
$8.22$
笔试 + 打电动。
但是因为明天是 $\operatorname{Day1}$,所以 $22:00$ 就睡了。
$8.23$
早上 $6:00$ 就起来了,考试的时候脑子比较清醒。
考前以为 $\operatorname{Day1}$ 会像之前一样简单。
这次没有任何意外,在 $8:00$ 准时开考。
我先把所有题读了一遍,感觉这 T3 说是 lxl 出的我也信。但 lxl 肯定不是出题人,所以根据经验肯定就是 zx2003 出的了!
一开始 T1 想到一个神秘随机化做法,不过感觉没啥前途。不久后就会 T1 的线并+链表了,并在 $8:45$ 过了所有样例。
T2 第一眼看上去是一个很 AGC 风格的计数题,首先肯定要分析什么样的序列可以被操作完。结果直接狂想 1h 毫无思路。
此时感觉这个题目的条件非常奇怪,显得很不优美,开始怀疑这是个 dp 套 dp 题。
然后就开始了最离谱的阶段:首先我忘了题目是要求**恰好**而不是**至多**,然后我直接猜出经过一个点的横向区间个数不超过 $3$。写了个判断是否合法的 dp 拿 $3$ 和 $20$ 对拍了一下,发现能拍上。
此时我感觉到赚大了,抱着拿 $k\le 2$ 分数的心态去写了个爆搜出所有可达状态的自动机,结果把 $k=100$ 塞进去一跑只有 $9960$ 个点!
去上了个厕所冷静下来之后开始着手把自动机用于 dp,这并不难写,过了不久就把除了第一个样例之外的都过了。
这时候我终于想起来原来是**恰好**,然后仔细分析了一下发现只需要判断 $2$ 种很简单的情况就行了。
然后我就用纯纯的狗运过了这道题。
这时已经只剩 1h 了,我先把 T3 最好写的 $10$ 分打了,然后出于求稳的心态回去检查 T1。结果这个轻松过了所有大样例的程序被我肉眼查出 $3$ 个错,只能说非常恐怖,还好去检查了。后来发现这大样例连个 $2$ 操作都没有。。。
出来的时候预估 $100+100+10=210$,听说大家好像都不会 T2 感觉属实赚麻了。
没有挂分,估计是在 ZR 掉的 $100+$ 分显灵了吧!
$8.24$
打电动。
本来想打牌,结果人没凑齐,只好决定考完后一起大玩特玩/kk
感觉逐渐对电动失去了兴趣。
与 $8.22$ 一样 $22:00$ 就睡了。
$8.25$
依然与 $\operatorname{Day1}$ 一样 $6:00$ 就起了,但是考试的时候头稍稍有点小晕。
因为 $\operatorname{Day1}$ 我建立了一定优势,所以今天还是稳为上策。
做 T1 的时候一直以为爆搜是过不了的,于是加了一些很有道理的剪枝优化了一下就感觉很稳了,但是自然溢出实在 fw,稍大一点的样例就能把它卡爆,换成双哈希就行了。
T2 是个很神秘的题,感觉很难 dp,可能可以贪心,但是思考一段时间无果,主要原因是主观上很难相信做法的正确性。然后我就把 $60$ 分的暴力全部打掉就跳过了。
T3 更为厉害,一看就是不太可做的题,先把 $k^n$ 的裸暴力打了,预计 $4$ 分。又往网络流的角度想了一会儿但完全不会,各种特殊性质也是不太容易。
剩下的 1h 我都在检查代码和想部分分两件事中间徘徊,但啥都没干成/ll
出考场的时候才意识到自己打的有点搞笑,T2 好像人均会,预估 $100+60+4=164$。
最终的结果还是比较可接受的,挂了 $-17$ 分,原因是 T3 的爆搜出人意料地跑得飞快,可能是数据比较水的缘故吧。于是 $4\rightarrow 21,164\rightarrow 181$。
考完出来突然接到通知要紧急疏散,没牌打了/ll/ll/ll
不过这个队应该还是进了,感觉很魔幻。
两天总分:$100+100+10+100+60+21=210+181=391$,很明显是输在 D2T2 上了。
upd: rk4。
今年是 ix35 的最后一次 NOI,明年这时候他 AK 完 IOI 就要退役了/ll。作为一个和他从普及组开始一直一起学到现在的 OIer 不免有些感慨。好像 ix35 不久前还是 NOI 2020 的一匹黑马,杀穿全场,现在却已经迎来了 OI 生涯的最后一次 NOI。真可谓流年似水,岁月如歌。OI 选手的更新换代太迅速了,一切就像一个很梦幻的故事,感觉不太真实,却又是时时刻刻在我们身边发生着的。我可怜的语言能力不允许我表达出所有想要说的东西,就在这里祝 ix35 未来好运吧!
Goodbye ix35!

最近给家里几台闲置机器拆开重新整理了一下,然后统统装上了 Proxmox 做虚拟化,然后开出小鸡来想着搞点没玩过的东西玩玩,四下看了看于是决定用 openSUSE Kubic 来装个 Kubernetes 集群来图一乐。
本文假设读者有在一台没有安装任何操作系统的计算机上安装 openSUSE 或其它主流 Linux 发行版的能力,并且假设读者具备一定的 Linux 使用经验,以及对 Kubernetes 有基本的了解。阅读本文还可能会需要一些计算机网络的基础知识。
本文同时发表在 我自己的博客。
openSUSE Kubic
这是一个 openSUSE 社区提供的衍生发行版,基于 openSUSE MicroOS 并预装了 Kubic 环境,可以较为方便地部署 Kubernetes 环境。和 openSUSE 本体的主要区别大概有两点,一是使用 openSUSE MicroOS 作为基础所以整个系统是 “事务式更新” 的,另一个就是预装了 Kubic 环境,不需要自己安装 Kubernetes 相关的各种工具。
openSUSE MicroOS 与 “事务式更新”
大体说来,openSUSE MicroOS 是一个针对专用场景(也就是说不是一般性的个人桌面应用)设计的偏轻量化和可靠性的基底系统,在 Wiki 页面上可以看到比较详细的介绍,不过就我个人的感受来看,最主要的区别和特色在于它的 “事务式更新” 机制。
“事务式更新” 是一个利用文件系统 “写入时复制” (Copy-on-write, CoW) 功能来隔离单次运行中对系统做出的修改的机制,从效果上有点类似于高级版的 “还原卡”。即每次系统更新都写到一个新的文件系统快照 (Snapshot) 中,当前运行中的系统对该新快照中的内容并不感知,而是直到下次重启系统时,从新的快照启动更新后的系统;如果新的系统存在异常,可以再次重启并在启动菜单选择上一个快照启动,实现回滚。这个行为和数据库中 “事务” 的概念如出一辙,将系统更新的若干过程包装成原子操作,可以避免系统进入到 “更新到一半某个地方坏掉了但一下子修不好又回不去” 的尴尬状况,所以名字也算是比较贴切了。
目前 openSUSE MicroOS 自己的实现 是基于 Btrfs 来做的,理论上这套工具也可以移植到其他支持 CoW 的文件系统上,并且实际上利用文件系统快照功能来实现备份和回滚都不是什么新鲜点子,也有不少人自己写脚本实现了类似的功能,但 MicroOS 这套工具胜在将其标准化和集成到了发行版中,目前也没看到有别的发行版在搞类似的东西,所以可以算是一大特色。
从用户角度看,这玩意带来的主要区别在于:
更新系统不能直接 zypper dup, 而是要先执行 transactional-update shell 再在新打开的 shell 中执行更新命令。(当然实际上 transactional-update 本身就是执行 zypper ref && zypper dup, 但如果要单独安装某个包就只能先进 shell 了)
更新、安装、卸载,以及修改重要的配置等操作后退出该 shell, 会发现系统还是进入 transactional update shell 之前的样子,所有修改仿佛不存在,要到下一次系统启动才会生效
如果希望在重启系统之前继续修改某个快照的内容,可以用 transactional-update -c xx shell 来进行,其中 xx 是快照编号,可以在每次进入和退出 transactional update shell 的时候看到
使用 transactional-update cleanup 可以清理所有未使用(非当前启动的)快照、释放磁盘空间
还有不少参数和子命令可以用 transactional-update -h 查看,不过我自己是觉得有了 shell 就什么都能做了(
Kubic
一句话说来就是一个在 openSUSE MicroOS 上预装了 kubeadm 和一些其他周边工具,针对容器平台宿主机这个特定场景的衍生发行版。整个衍生关系大概是这样的:openSUSE Tumbleweed -> openSUSE MicroOS -> openSUSE Kubic.
openSUSE Kubic 使用了一个叫 Salt 的运维工具来实现多节点间的控制,并且在上面包了一个叫 kubic-control 的工具提供 kubicctl 以及其它一些相关的命令。默认使用 cri-o 代替知名度更大一些(但逐渐商业化)的 Docker 作为容器运行时。
整个集群的架构是一个 Kubic Admin 节点和若干个普通 Kubic 节点,通过 Salt 实现了鉴权打通后可以直接在 Kubic Admin 上通过 kubicctl 等命令来自动配置所有需要的节点,具体步骤之后会有例子。
安装系统
接下来实际部署一个 Kubic 集群看看。首先安装的是 Kubic Admin, 这个节点也会被作为 Kubernetes master.
需要注意所有节点的主机名一定要是在当前网络内可解析的 FQDN, 安装完成后不要随意修改,否则可能会造成一些奇怪的问题。
以下部分步骤有截图,来自我在虚拟机里面安装系统的过程,和最新的安装向导不一定完全一致,参考进行即可。整个安装过程都是图形化向导,步骤也并不多。
首先是选择安装角色,不同选项代表了不同的预装软件和配置集合。
第一个节点选 Kubic Admin Node, 之后安装的其它节点选 Addional Kubic Node.
选区_3021279×954 188 KB
如果需要部署多 master 集群,还需要安装一台 Kubic Loadbalancer Node 配置 haproxy, 这个 haproxy 也可以部署在其他任意地方,也不限于 haproxy 本身,任意可以反向代理 HTTPS 请求的负载均衡软件或设备均可。其反代的目标是所有 Kubernetes Master 节点的 6443 端口,即 Kubernetes Control Plane. 之后整个集群和所有的客户端都会通过这个负载均衡器来访问 Control Plane, 它的域名也需要在当前网络中可以解析,且不能随意更改。
之后在配置界面修改时区为需要的时区,并且修改网络配置为静态 IP 地址。修改网络配置时最好在 IP 地址设置和 DNS 设置中将主机名都填写成机器的 FQDN, 并且可能需要添加一条默认路由。
选区_3031278×953 162 KB
然后就可以点击 Install 进行安装了。完成后会自动重启。
选区_3041276×954 31.6 KB
进入系统后先 transactional-update shell 然后 zypper ref && zypper dup 更新系统,并且安装需要的软件包以及按需调整系统配置,比如我会安装 fail2ban 并设置其开机启动,以及由于家里网络环境的需要会修改 /etc/sysctl.conf 禁用掉 IPv6. 完成系统更新和配置后退出 transactional update shell, 重启系统。
再次进入系统后检查各项配置是否正确,然后可以用 transactional-update cleanup 清除之前的旧快照。之后的每一个节点安装后都推荐进行系统更新与配置的操作,不再重复说明。
如果安装后无法 SSH 登录机器,可以修改/新建 /etc/ssh/sshd_config.d/rootlogin.conf 文件添加一行 PermitRootLogin yes 再重启 sshd.service 后使用。
初始化 Kubernetes 集群
在安装好 Kubic Admin 和配置好负载均衡(如果部署单 master 的 Kubernetes 集群则不需要负载均衡器)后即可初始化 Kubernetes 集群。
初始化 Kubernetes 集群的操作通过 kubicctl init 命令完成,如果需要设置集群的一些属性(比如 Kubernetes 版本,默认是装当前的最新版)可以通过参数指定,具体看 kubicctl -h 的帮助即可。由于这里我要部署一个多 master 的高可用 Kubernetes 集群,所以还需要加上 --multi-master 参数,其值为负载均衡器的域名。
kubic-master-fenrir:~ # kubicctl init --multi-master kubic-lb-m31.home.atr.moe
Initializing kubernetes master can take several minutes, please be patient.
Setting up multi-master kubernetes node (reacheable as 'kubic-lb-m31.home.atr.moe') with weave
Initialize Kubernetes control-plane
Deploy weave
Deploy Kubernetes Reboot Daemon (kured)
First Kubernetes master succesfully setup.
Please add at minimum two further master nodes!
如果 kubicctl init 的过程卡住,或者干脆超时报错,则需要对 registry.opensuse.org 施放魔法。具体操作不赘述,但推荐将魔法阵部署在网关上以向节点提供透明的冲浪体验。
在集群初始化完成后,即可通过以下操作获取 kubeconfig 文件,并且可以用 kubectl 查看当前的集群状态了:
kubic-master-fenrir:~ # mkdir .kube
kubic-master-fenrir:~ # kubicctl kubeconfig > .kube/config
kubic-master-fenrir:~ # kubectl get no
NAME STATUS ROLES AGE VERSION
kubic-master-fenrir NotReady control-plane,master 47s v1.20.2
向 Kubernetes 集群添加更多节点
如果之前还没有给 Kubic Admin 以外的节点装机,那现在就是时候动手了。按照我的预期拓扑,至少还需要两台 Kubernetes Master 节点,和若干 Kubernetes Worker 节点。所有这些节点的装机方法是一样的。
进入到安装向导,安装类型选择 Addional Kubic Node, 并在下一个界面填写 Kubic Admin 节点的域名(注意不是负载均衡器的域名)。
选区_3061283×958 188 KB
之后同样是配置时区、网络等操作,和安装 Kubic Admin 节点时雷同。
在完成所有剩余节点的系统安装和配置之后,回到第一台,也就是 Kubic Admin 节点,开始向集群中添加节点。
首先是执行 salt-key -L 查看当前的所有节点列表,检查是否正确,如果有误则到对应机器上修改 /etc/salt 下的配置文件并重启 salt-minion 服务。如果是修改节点名称,可以在确认新节点已经出现在 salt-key -L 的 Unaccepted Keys 列表之后用 salt-key -d xxx 命令来删除旧的记录。
确认列表无误后执行 salt-key -A 接受所有 key, 也可以用 -a xxx 参数来一个一个接受。
然后使用 kubicctl node add 命令来添加剩余的两台 Kubernetes Master 节点:
kubic-master-fenrir:~ # kubicctl node add --type master kubic-master-janus.home.atr.moe
Upload certificates ...
kubic-master-janus.home.atr.moe: adding node...
kubic-master-janus.home.atr.moe: joining cluster...
kubic-master-janus.home.atr.moe: node successful added
Node(s) successfully added
添加 Kubernetes Master 节点需要一台一台操作,添加的对象是 salt-key -L 中看到的节点名称,正常情况下它应该和该节点的 FQDN 是一样的。
完成后即可看到相应节点的状态:
kubic-master-fenrir:~ # kubectl get no
NAME STATUS ROLES AGE VERSION
kubic-master-fenrir Ready control-plane,master 15m v1.20.2
kubic-master-janus Ready control-plane,master 7m42s v1.20.2
kubic-master-narvi Ready control-plane,master 4m20s v1.20.2
此时应当检查负载均衡器的设置,将三台 master 都添加到反代后端中。(之前的操作只需要有第一台节点在反代后端中即可完成)
添加多台 worker 节点可以在一条命令中完成(当然分开也没关系),多个节点间使用逗号分割即可:
kubic-master-fenrir:~ # kubicctl node add kubic-worker-fenrir.home.atr.moe,kubic-worker.janus.home.atr.moe
kubic-worker.janus.home.atr.moe: adding node...
kubic-worker-fenrir.home.atr.moe: adding node...
kubic-worker.janus.home.atr.moe: joining cluster...
kubic-worker-fenrir.home.atr.moe: joining cluster...
kubic-worker.janus.home.atr.moe: node successful added
kubic-worker-fenrir.home.atr.moe: node successful added
Node(s) successfully added
如果添加 node 失败或者其他原因玩脱了,可以 kubectl delete node xxx 删除该 node, 再登录到对应机器上 kubeadmin reset 清空配置,然后就可以回到 Kubic Admin 上重新使用 kubicctl 添加了。
一切完成后通过 kubectl 即可正常操作 Kubernetes 集群:
kubic-master-fenrir:~ # kubectl get no
NAME STATUS ROLES AGE VERSION
kubic-master-fenrir Ready control-plane,master 59m v1.20.2
kubic-master-janus Ready control-plane,master 55m v1.20.2
kubic-master-narvi Ready control-plane,master 52m v1.20.2
kubic-worker-fenrir Ready
kubic-worker-janus Ready
kubic-worker-narvi Ready
Have a lot of fun~

请问 Kubic Loadbalancer Node 是怎么配置的?

我没有用它自带的那个 Loadbalancer Node, 是在另外一台虚机上配了 haproxy. 从我看的情况,它那个 Loadbalancer Node 其实也就是个预装好 haproxy 的 MicroOS 系统。
需要配置的是以 TCP 方式反代 6443 端口到三台 k8s master, 然后给这个 loadbalancer 机子配置一个域名,并且用这个域名作为后面 kubicctl init 时候使用的地址
这个反代也不必要是 haproxy, 用别的反向代理软件或者硬件应该也是可以的

Jan 2019 | Douglas DeMaio | No License Published by Richard Brown on Jan 22, 2019 on kubic.opensuse.org The openSUSE Kubic team is proud to announce that as of yesterday, our Kubic distribution has become a Certified Kubernetes Distribution! Notably, it is the first open source Kubernetes distribution to be certified using the CRI-O container runtime! What is Kubernetes Certification? Container technologies in general, and Kubernetes in particular, are becoming increasingly common and widely adopted by enthusiasts, developers, and companies across the globe. A large ecosystem of software and solutions is evolving around these technologies. More and more developers are thinking “Cloud Nativeâ€� and producing their software in containers first, often targeting Kubernetes as their intended platform for orchestrating those containers. And put bluntly, they want their software to work. But Kubernetes isn’t like some other software with this sort of broad adoption. Even though it’s being used in scenarios large and small, from small developer labs to large production infrastructure systems, Kubernetes is still a fast-moving project, with new versions appearing very often and a support lifespan shorter than other similar projects. This presents real challenges for people who want to download, deploy and run Kubernetes clusters and know they can run the things they want on top of it. When you consider the fast moving codebase and the diverse range of solutions providing or integrating with Kubernetes, that is a lot of moving parts provided by a lot of people. That can feel risky to some people, and lead to doubt that something built for Kubernetes today might not work tomorrow. Thankfully, this a problem the Cloud Native Computing Foundation (CNCF) is tackling. The CNCF helps to build a community around open source container software, and established the Kubernetes Software Conformance Certification to further that goal. Certified Kubernetes solutions are validated by the CNCF. They check that versions, APIs, and such are all correct, present, and working as expected so users and developers can be assured their Kubernetes-based solutions will work with ease, now and into the future. Why Certify Kubic? The openSUSE Project has a long history of tackling the problem of distributing fast-moving software. Tumbleweed and Kubic are simultaneously both two of the fastest and most stable rolling release distributions available. With the Open Build Service and openQA we have an established pipeline that guarantees we only release software when it is built and tested both collectively and reproducibly. Our experience with btrfs and snapper means that even in the event of an unwanted (or heaven forbid, broken) change to a system, users can immediately rollback to a system state that works the way they want it to. With Transactional Updates, we ensure that no change ever happens to a running system. This futher guarantees that any rollback can return a system to a clean state in a single atomic operation. In Kubic, we leverage all of this to build an excellent container operating system, providing users with the latest versions of exciting new tools like Podman, CRI-O, Buildah, and (of course) Kubernetes. We’re keeping up with all of those fast moving upstream projects, often releasing our packages within days or sometimes even hours of an upstream release. But we’re careful not to put users at risk, releasing Kubic in sync with the larger openSUSE Tumbleweed distribution, sharing the same test and release pipeline, so we can be sure if either distribution makes changes that breaks the other, neither ships anything to users. So we’ve solved all the problems with fast moving software, so why certify? 😉 Well, as much as it pains me to write this, no matter how great we are with code review, building, testing and releasing we’re never going to catch everything. Even if we did, at the end of the day, all we can really say is “we do awesome stuff, trust usâ€� And when you consider how we work in openSUSE, things can seem even more complicated to newcomers. We’re not like other open source projects with a corporate backer holding the reigns and tightly controlling what we do. openSUSE is a truly open source community project where anyone and everyone can contribute, taking what we’re doing in Kubic, and directly changing it to fit what they want to see. These contributions are on an equal playing field, with SUSE and other Sponsors of openSUSE having to contribute in just the same way as any other community member. And we want more contributions. We will keep Kubic open and welcoming to whatever crazy (or smart, or crazy-smart) ideas you might have for our container distribution. But we also want everyone else to know that whatever we end up doing, people can rely on Kubic to get stuff done. By certifying Kubic with the CNCF, there is now an impartial third party who has looked over what we do, checked what we’re distributing, checked our documentation, and conferred to us their seal of approval. So, to everyone who has contributed to Kubic so far and made this possible, THANK YOU. To all of the upstream projects without whom Kubic wouldn’t have anything to distribute and get certified, THANK YOU and see you soon on your issue trackers and pull request queues. And to anyone and everyone else, THANK YOU, and we hope you have a lot of fun downloading, using, and hopefully contributing back our window into the container world.

Mar 2018 | The Kubic Team | No License Welcome to the webpage and inaugural blog post of the Kubic Project. This post should serve as a basic introduction to Kubic for anyone interested in what we’re doing. What is Kubic? The Kubic Project is a sub-project of the broader openSUSE Project. We’re focused on new and emerging technologies surrounding containers. We’re exploring, developing, adapting and integrating these technologies, helping bring them to the world of openSUSE and helping to improve them directly in their respective upstream projects. Many of these technologies also serve as upstreams for SUSE’s CaaS Platform Product. Why? To put it simply, because these technologies are fun. But to try and be a little serious, the ongoing trends with Containers, Micro-Services, and alternative methods of application delivery are disruptive and changing peoples’ expectations. Instead of complicated manual setups, a growing number of apps & services are just a simple ‘pull’ away, and this changes what users need and expect from their operating systems & surrounding tooling. The Kubic Project aims to be at the forefront of these trends, taking the best of these new concepts and bringing them to openSUSE while also helping adjust openSUSE to best support these new technologies. What are we working on? As of March 2018 we’re currently working on: Transactional Updates MicroOS Tumbleweed Kubic Velum Alternative Container Runtimes (CRI-O, Podman) Rootless Containers As the world of containers moves very quickly, this list is bound to be incomplete and incorrect for readers in the future, but below is a brief summary of each to give a flavour of what we’re working on. Transactional Updates transactional-update is a command-line tool that brings atomic updates to openSUSE & SUSE distributions. It leverages our long experience with btrfs, zypper and snapper to update a system without touching the running system. All package updates are prepared as a single operation in a btrfs snapshot. This snapshot is not used until the next reboot. Any problems can be immediately rolled back by discarding this transactional snapshot and rebooting again, instantly returning the system to its working order. When coupled with a read-only root filesystem, users are left with a robust running operating system that they can be confident will not change in any way at all while it’s running, and can be confidently returned to working order if updates have unintended side-effects. Transactional Updates with read-only root filesystem are currently available by default in Tumbleweed Kubic and will soon be available as an installation option in both openSUSE Tumbleweed and openSUSE Leap 15. MicroOS MicroOS is the base system for Tumbleweed Kubic. It is an openSUSE Tumbleweed derivative designed to run containers and optimised for large deployments. It includes both a read-only root filesystem and fully automated transactional updates out of the box. Its development and release is fully aligned and tested as part of Tumbleweed, meaning any new Tumbleweed release automatically includes updates to Kubic’s MicroOS. MicroOS can currently be installed as by selecting the System Role when installing Tumbleweed Kubic. In the future we also intend to offer VM images. Tumbleweed Kubic Tumbleweed Kubic is our Container-as-a-Service Platform using Kubernetes atop MicroOS. In addition to the MicroOS System Role, Tumbleweed Kubic currently offers the Unconfigured Cluster Node role, allowing users to get started with setting up their own Kubernetes Cluster. In the future Tumbleweed Kubic will also offer a further streamlined and automated cluster configuration workflow based on Velum. Velum Velum is our Cluster Dashboard & Bootstrap Tool which will allow you to: Bootstrap a Kubernetes Cluster in a simple WebUI Manage your cluster, including adding & removing nodes, monitor faulty nodes, etc. Setup an update policy to help define when and how you want Transactional Update to run across your cluster. Velum is under active development and we are hopeful to offer Tumbleweed Kubic images containing Velum in the near future. Alternative Container Runtimes We are currently investigating alternative container runtimes such as CRI-O and its companion tooling Podman as more lightweight option for running containers both within Kubernetes and as a stand-alone runtime. Both are already available in both Tumbleweed & Tumbleweed Kubic today. Rootless Containers This is a project that was spear-headed by our team (based on the work of the larger container community). The idea was to allow completely unprivileged users to create containers on their own machines using a standardised container runtime (runc). We also wrote umoci which allows unprivileged (and privileged) users to operate easily on OCI images. Currently the main interest being worked on (along with some of the containers community) is the ability to have unprivileged networking using TAP. This would (theoretically) push us closer to having the possibility of a rootless Kubernetes deployment. You can keep a close eye on rootlesscontaine.rs if you’re interested in more about this effort. Rootless containers already work flawlessly on all modern openSUSE distributions. How can I get involved? Most importantly, like every openSUSE Project, Kubic is an open community. We would like your help. Our sources can be found on GitHub. If you’re interested in helping us on anything mentioned here, or have ideas on what we should be looking at, then please get in touch either on our Mailing List or on IRC where you can find us in #Kubic on Freenode.
