Digital Ocean and Docker Machine test environment (FREE SELF)
This guide is for quickly testing different versions of GitLab and not recommended for ease of future upgrades or keeping the data you create.
Initial setup
This guide configures a Digital Ocean droplet and sets up Docker locally on either macOS or Linux.
On macOS
Install Docker Desktop
On Linux
Install Docker Engine
Install Docker Machine
NOTE: The rest of the steps are identical for macOS and Linux.
Create new Docker host
-
Login to Digital Ocean.
-
Generate a new API token at https://cloud.digitalocean.com/settings/api/tokens.
This command creates a new Digital Ocean droplet called
gitlab-test-env-do
that acts as a Docker host.NOTE: 4GB is the minimum requirement for a Docker host that runs more than one GitLab instance.
- RAM: 4GB
- Name:
gitlab-test-env-do
- Driver:
digitalocean
-
Set the DO token:
export DOTOKEN=<your generated token>
-
Create the machine:
docker-machine create \ --driver digitalocean \ --digitalocean-access-token=$DOTOKEN \ --digitalocean-size "4gb" \ gitlab-test-env-do
Resource: https://docs.docker.com/machine/drivers/digital-ocean/.
Creating GitLab test instance
Connect your shell to the new machine
This example creates a GitLab EE 8.10.8 instance.
First connect the Docker client to the Docker host you created previously.
eval "$(docker-machine env gitlab-test-env-do)"
You can add this to your ~/.bash_profile
file to ensure the docker
client uses the gitlab-test-env-do
Docker host
Create new GitLab container
- HTTP port:
8888
- SSH port:
2222
- Set
gitlab_shell_ssh_port
using--env GITLAB_OMNIBUS_CONFIG
- Set
- Hostname: IP of Docker host
- Container name:
gitlab-test-8.10
- GitLab version: EE
8.10.8-ee.0
Set up container settings
export SSH_PORT=2222
export HTTP_PORT=8888
export VERSION=8.10.8-ee.0
export NAME=gitlab-test-8.10
Create container
docker run --detach \
--env GITLAB_OMNIBUS_CONFIG="external_url 'http://$(docker-machine ip gitlab-test-env-do):$HTTP_PORT'; gitlab_rails['gitlab_shell_ssh_port'] = $SSH_PORT;" \
--hostname $(docker-machine ip gitlab-test-env-do) \
-p $HTTP_PORT:$HTTP_PORT -p $SSH_PORT:22 \
--name $NAME \
gitlab/gitlab-ee:$VERSION
Connect to the GitLab container
Retrieve the Docker host IP
docker-machine ip gitlab-test-env-do
# example output: 192.168.151.134

.
Execute interactive shell/edit configuration
docker exec -it $NAME /bin/bash
