用Testcontainers进行多级构建

Question

我试图在多阶段构建Dockerfile中使用Testcontainers，目前它在以下方面失败：

ERROR   --- [           main] o.t.d.DockerClientProviderStrategy       : Could not find a valid Docker environment. Please check configuration. Attempted configurations were:
ERROR   --- [           main] o.t.d.DockerClientProviderStrategy       :     UnixSocketClientProviderStrategy: failed with exception InvalidConfigurationException (Could not find unix domain socket). Root cause NoSuchFileException (/var/run/docker.sock)
ERROR   --- [           main] o.t.d.DockerClientProviderStrategy       : As no valid configuration was found, execution cannot continue

是否有一种方法可以在多级构建中挂载/var/run/docker.sock？或者，除了必须挂载docker.sock之外，还有其他选择吗？

Answer 1

据我所知，在当前时间点上访问Docker (特别是/var/run/docker.sock主机的Docker套接字)是不可能的。但是，您可以将Docker构建配置为通过网络访问守护进程，如this应答中所述。
