问题

Java代码中使用testcontainers启动报错

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

原因

MacBook 在Docker Desktop 4.12版本之后不会默认创建/var/run/docker.sock

解决方法

在Docker Desktop中启用

然后点击Apply & restart
就可以找到这个文件了

 mac@MacBook-Pro  ~  ls /var/run/docker.sock
/var/run/docker.sock
