Unable to reach LocalStack when running it with colima

LocalStack colima could not connect to LocalStack health endpoint

3 min read | by Jordi Prats

If we try to run localstack using colima we might face the following error:

$ localstack status services
✖ ERROR: could not connect to LocalStack health endpoint at http://localhost:4566

Because enabling a reachable IP address would have an impact on the startup time, by default colima doesn't expose any IP address. To fix it we just need to add the --network-address to the colima start command:

$ colima stop
INFO[0000] stopping colima
INFO[0000] stopping ...                                  context=docker
INFO[0012] stopping ...                                  context=vm
INFO[0016] done
$ colima start --network-address
INFO[0000] starting colima
INFO[0000] runtime: docker
INFO[0000] preparing network ...                         context=vm
INFO[0000] dependencies missing for setting up reachable IP address  context=vm
INFO[0000] sudo password may be required                 context=vm
INFO[0003] starting ...                                  context=vm
INFO[0037] provisioning ...                              context=docker
INFO[0037] starting ...                                  context=docker
INFO[0042] done

Or use the --edit flag to update the option to true:

$ colima start -e

Once enabled, if we run again the localstack status services, we'll be able to reach LocalStack:

$ localstack status services
