docker - DOCKER_TLS_VERIFY 和 DOCKER_CERT_PATH 变量有什么作用？

Question

我是 Docker 新手，在 Windows 7 上使用 boot2docker。
当我尝试通过 spotify maven 插件配置 Docker 构建时，我被要求设置以下 env 变量:

DOCKER_HOST
DOCKER_CERT_PATH
DOCKER_TLS_VERIFY

配置成功但不确定DOCKER_TLS_VERIFY 和 DOCKER_CERT_PATH 变量有什么作用？

Answer 1

作为 mentioned in the README :

By default, boot2docker runs docker with TLS enabled. It auto-generates certificates and stores them in /home/docker/.docker inside the VM.
The boot2docker up command will copy them to ~/.boot2docker/certs on the host machine once the VM has started, and output the correct values for the DOCKER_CERT_PATH and DOCKER_TLS_VERIFY environment variables.

eval "$(boot2docker shellinit)" will also set them correctly.

We strongly recommend against running Boot2Docker with an unencrypted Docker socket for security reasons, but if you have tools that cannot be easily switched, you can disable it by adding DOCKER_TLS=no to your /var/lib/boot2docker/profile file.

在更动态的环境中，boot2docker ip 可以更改，请参阅 issue 944 .
