# Install gitlab dockerized

export GITLAB_HOME=/srv/gitlab

gitlab/gitlab-ee:latest

# Takes a long time, lookup with 

sudo docker logs -f gitlab

# When it looks ready, do

sudo docker exec -it gitlab grep 'Password:' /etc/gitlab/initial_root_password

# to get the admin password so you can approve the new account. Do the account as your github username/password preferably

# Install virtualbox
# Install Ubuntu on virtualbox, and remove /home/$USER/.bash_logout file
# Install Windows on virtualbox, and follow https://docs.gitlab.com/runner/executors/virtualbox.html#checklist-for-windows-vms
# Do https://superuser.com/a/1606548 on windows
# Run `[System.Security.Principal.WindowsIdentity]::GetCurrent().Name` on windows to get the ssh machine machine/username and put into the registered instance (is it really needed? I dont think so)
# Do as admin:
reg add HKLM\SOFTWARE\OpenSSH /v DefaultShell /d C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe
# Install https://git-for-windows.github.io/ with the bash option so bash is available on power shell (IMPORTANT!)
# Register a runner instance (get the instance token on the panel and substitute below, ALSO edit the URL)

# For registering a docker instance (don't do this for virtual box vms)
docker run --rm -v /srv/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register \
--non-interactive \
--executor "docker" \
--docker-image alpine:latest \
--url "http://192.168.1.11" \
--registration-token "PROJECT_REGISTRATION_TOKEN" \
--description "docker-runner" \
--maintenance-note "Free-form maintainer notes about this runner" \
--tag-list "docker,aws" \
--run-untagged="true" \
--locked="false" \
--access-level="not_protected"

# I think it's better to install the runner without docker, cause the docker one cannot find virtualbox
curl -LJO https://gitlab-runner-downloads.s3.amazonaws.com/latest/deb/gitlab-runner_amd64.deb
sudo apt install -y ./gitlab-runner_amd64.deb 

# For registering a virtualbox instance interatively with docker (does not work after)
docker run --rm -it -v /srv/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register

# For registering a virtualbox runner without docker

gitlab-runner register

# Add the `disable_strict_host_key_checking = true` line to `.gitlab-runner/config.toml` like this:

concurrent = 1
check_interval = 0

[session_server]
session_timeout = 1800

[runners.ssh]
  user = "lz"
  password = ""
  disable_strict_host_key_checking = true

Also add the cache directory to the runners section
  cache_dir = "/home/your_username/cache"
  output_limit = 90000

  
example:

[[runners]]
  name = "virtualbox_nondocker"
  url = "http://192.168.1.20/"
  token = "..."
  executor = "virtualbox"
  cache_dir = "/home/lz/cache"
  output_limit = 90000




# Create runner user

useradd gitlab-runner

# Add the runner user to docker

sudo usermod -aG docker gitlab-runner

# Verify that it works (that is, the runner can access docker)

sudo -u gitlab-runner -H docker info
