Docker学习7-jenkins容器内安装python3

阅读更多关于 Docker学习7-jenkins容器内安装python3

前言很多小伙伴可能在考虑 jenkins 拉取了 github 上的代码后，发现还越少 python3 环境，那能怎么办呢？咨询了一位运维朋友给我的答案是，将 python3 挂载到容器工作目录上，或者直接复制。一、浅谈容器内安装 python3 方案 1、将 python3 挂载到容器工作目录上； 2、直接复制 python3 目录到工作目录上； 3、jenkins 容器内安装 python3；结果：1 、2均均阵亡，为何？明显系统不一样哈，虽然能在命令行中输入 python3 但是 pip3用不了的，执行脚本更是乱七八糟的报错。（所以不推荐）最后只能看 3 的了。然后在试验的过程中，发现第3种又分为两种， ① weget 安装（不推荐，基本和现安装的方法差不多，先要安装一些依赖包，如 gcc 等） ② apk add 安装（此版本是alpine ：apk add，能够快速安装完成）最后注意系统版本问题：如果是 centos 那即是 yum 如果是 ubuntu 那即是 apt-get 如果是 alpine 那即是 apk 二、apk add 安装 1、进入 jenkins 容器 bash： [root@iZbp19lugf22zbsubsf1y6Z ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS

Missing packages folder and smart.json file in Meteor.js 0.9

问题 It may be a dumb question but I upgraded meteor.js to meteor 0.9 and now, when I add packages, I do not see /packages folder or smart.json file in the root of my project. How can I reach to the source code of the downloaded packages. Thank you. 回答1: The source code of the downloaded packages is in a semi compiled state, nothing like what you would find on github. To access these have a look at ~/.meteor/packages . You would find them with the new notation e.g for iron:router you would see

Does the star import include subpackages in Java?

阅读更多关于 Does the star import include subpackages in Java?

问题 When you declare an import like this: import com.microsoft.azure.storage.*; Does that include everything in its subpackages too? For example, does it include this? import com.microsoft.azure.storage.blob.* If not, why not? (Edit: the "why" question is basically off topic. ignoring that bit when considering a correct answer.) 回答1: No it does not. It only imports everything in the package (i.e. the directory itself). Sub-directories are considered to be different packages, so you would need to:
