非阿尔卑斯丁德码头形象

Question

是否存在现有的非Alpine dind docker映像？

绑定安装主机的docker插座对我不起作用。我需要合适的dind。Docker的dind图像似乎都是基于Alpine的，这对我来说也不起作用。

Answer 1

不完全是您问题的答案，但可能会解决您的需求：

我认为您并不真正需要非Alpine，而是需要启用GLIBC的映像。

我想要一个支持Docker的Gitlab CI的Docker镜像，它将拥有OpenJDK 12。这样的镜像还不可用——AdoptOpenJDK镜像没有DinD，官方的docker:*镜像也无法安装正常的OpenJDK。

所以我把adoptopenjdk:12和docker:stable结合起来，它似乎起作用了。

docker build --label docker-with-openjdk12 .

Answer 2

您只想运行Docker在Jenkins中执行CI系统（构建、运行、将容器映像推送到hub）。Jenkins Master将启动Jenkins Slave作为容器，并在其中执行CI操作。

是的，您可以在jenkins slave容器中运行docker命令

我们需要jenkins slave容器中的Docker二进制文件，在这里，当通过Docker文件创建Docker映像时，我们已经向其添加了Docker二进制文件。

一旦构建了镜像，我们只需要在容器/var/run/docker.sock上批量安装主机的Docker sock /var/run/docker.sock。

在这里，我们将从主机和Docker客户端执行Docker守护进程作为jenkins从属容器。
