Multistage Builds with Testcontainers

I'm trying to use Testcontainers inside the Multistage Build Dockerfile, and it's currently failing with :

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

Is there a way to mount /var/run/docker.sock in a Multistage build ? Or is there an alternative than having to mount the docker.sock ?

Solution

  • To my knowledge, accessing Docker (and specifically the Docker socket of the host at /var/run/docker.sock) is not trivially possible at the current point in time. However, you can configure the Docker build to access the daemon over the network, as outlined in this answer.
