How to set up Colima to work with testcontainers-node?

[wujekbogdan]

I managed to get it working by setting the following variables:

export TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE=/var/run/docker.sock
export TESTCONTAINERS_HOST_OVERRIDE=$(colima ls -j | jq -r '.address')
export DOCKER_HOST="unix://${HOME}/.colima/default/docker.sock"

together with the following config:

network:
  address: true

Only then my jest tests are running.

The problem is the following line:

export TESTCONTAINERS_HOST_OVERRIDE=$(colima ls -j | jq -r '.address')

Colima daemon boots at system startup thanks to a brew service:

brew services stop colima

So setting TESTCONTAINERS_HOST_OVERRIDE it in ~/.zshrc doesn't guarantee that Colima has already started when ~/.zshrc is being processed.

Is my setup overcomplicated? Is there an easier way to get Colima to work with testcontainers-node?

Hi @wujekbogdan, running testcontainers-node with Colima is documented here:
