# Digital Ocean and Docker Machine test environment
CAUTION: **Caution:**
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
In this guide you'll configure a Digital Ocean droplet and set up Docker
locally on either macOS or Linux.
### On macOS
#### Install Docker Toolbox
- <https://www.docker.com/products/docker-toolbox>
### On Linux
#### Install Docker Engine
- <https://docs.docker.com/engine/installation/linux/>
#### Install Docker Machine
- <https://docs.docker.com/machine/install-machine/>
NOTE: **Note:**
The rest of the steps are identical for macOS and Linux.
### Create new docker host
1. Login to Digital Ocean.
1. Generate a new API token at <https://cloud.digitalocean.com/settings/api/tokens>.
This command will create a new DO droplet called `gitlab-test-env-do` that will act as a docker host.
NOTE: **Note:**
4GB is the minimum requirement for a Docker host that will run more than one GitLab instance.
- RAM: 4GB
- Name: `gitlab-test-env-do`
- Driver: `digitalocean`
1. Set the DO token:
```sh
export DOTOKEN=<your generated token>
```
1. Create the machine:
```sh
docker-machine create \
--driver digitalocean \
--digitalocean-access-token=$DOTOKEN \
--digitalocean-size "4gb" \
gitlab-test-env-do
```
Resource: <https://docs.docker.com/machine/drivers/digital-ocean/>.
### Creating GitLab test instance
#### Connect your shell to the new machine
In this example we'll create a GitLab EE 8.10.8 instance.
First connect the docker client to the docker host you created previously.
```sh
eval "$(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`
- Hostname: IP of docker host
- Container name: `gitlab-test-8.10`
- GitLab version: **EE** `8.10.8-ee.0`
##### Set up container settings
```sh
export SSH_PORT=2222
export HTTP_PORT=8888
export VERSION=8.10.8-ee.0
export NAME=gitlab-test-8.10
```
##### Create container
```sh
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
```sh
docker-machine ip gitlab-test-env-do
# example output: 192.168.151.134
```
Browse to: <http://192.168.151.134:8888/>.
##### Execute interactive shell/edit configuration
```sh
docker exec -it $NAME /bin/bash
```
```sh
# example commands
root@192:/# vi /etc/gitlab/gitlab.rb
root@192:/# gitlab-ctl reconfigure
```
