Docker+machine executor creating too many instances
Summary
Using then docker+machine executor creates too many machines:
- When the limit is set to 4, it initially creates 5 machine instances and then scales down to 4.
- When the limit is set to 1, it initially creates 2 machine instances and then scales down to 1.
- When the limit is not set, it creates 2 machine instances.
Steps to reproduce (limit = 4)
Save the following in gitlab-runner/config.toml
:
concurrent = 10
check_interval = 1
[[runners]]
name = "runner-digitalocean-0"
limit = 4
url = "https://<gitlab-host>"
token = "cc70ebba48ed1b288af2..."
executor = "docker+machine"
[runners.docker]
tls_verify = false
image = "mediamoose/inner-ci:1.7"
privileged = false
disable_cache = true
volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
[runners.cache]
[runners.machine]

Apply docker-machine certificate generation workaround by mentioned in https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/2184 -> https://github.com/docker/machine/issues/4005:
docker run -it --rm -v $PWD/docker:/root/.docker --entrypoint docker-machine gitlab/gitlab-runner:alpine-v1.11.1 create -d none --url localhost test
docker run -it --rm -v $PWD/docker:/root/.docker --entrypoint docker-machine gitlab/gitlab-runner:alpine-v1.11.1 rm -f test
Start the runner:
docker run -it --rm \
-v $PWD/gitlab-runner:/etc/gitlab-runner \
-v $PWD/docker:/root/.docker \
gitlab/gitlab-runner:alpine-v1.11.1
Actual behavior
5 Instances are getting created.

Expected behavior
Just one DigitalOcean instance getting created (conform IdleCount = 1
).
