Installing Monica on Docker

You can use Docker and docker-compose to pull or build and run a Monica image, complete with a self-contained MySQL database. This has the nice properties that you don't have to install lots of software directly onto your system, and you can be up and running quickly with a known working environment.

Before you start, you need to get and edit a .env file. If you've already cloned the Monica Git repo, run:

cp .env.example .env

to create it. If not, you can fetch it from GitHub like:

curl -sS https://raw.githubusercontent.com/monicahq/monica/master/.env.example > .env

Then open .env in an editor and update it for your own needs:

  • Set APP_KEY to a random 32-character string. For example, if you have the pwgen utility installed, you could copy and paste the output of pwgen -s 32 1.
  • Edit the MAIL_* settings to point to your own mailserver.
  • Set DB_* settings to point to your database configuration. If you don't want to set a db prefix, be careful to set DB_PREFIX= and not DB_PREFIX='' as docker will not expand this as an empty string.

Note for macOS: you will need to stop Apache if you wish to have Monica available on port 80.

You can do this like so:

sudo /usr/sbin/apachectl stop

To start Apache up again use this command:

sudo /usr/sbin/apachectl start

Now select one of these methods to be up and running quickly:

Use docker-compose to run a pre-built image

This is the easiest and fastest way to try Monica! Use this process if you want to download the newest image from Docker Hub and run it with a pre-packaged MySQL database.

Start by fetching the latest docker-compose.yml and .env if you haven't done that already.

curl -sS https://raw.githubusercontent.com/monicahq/monica/master/docker-compose.yml > docker-compose.yml
curl -sS https://raw.githubusercontent.com/monicahq/monica/master/.env.example > .env

Edit the docker-compose.yml and change both the volumes on the monicahq service and the mysql service. Change the part before the : and point it to an existing, empty directory on your system. It is also be a good idea to change the webserver port from 80:80 to 3000:80.

Edit .env again to set DB_HOST=mysql (as mysql is the creative name of the MySQL container).

Start by downloading all the images and setup your new instance.

docker-compose pull
docker-compose up

Wait until all migrations are done and check if you can open up the login page by going to http://localhost:3000. If this looks ok, shut down the instance and add your first user account.

docker-compose run monicahq shell
php artisan setup:production
exit

Start your instance again with docker-compose up and login.

Use docker-compose to build and run your own image

Use this process if you want to modify Monica source code and build your image to run.

Edit .env again to set DB_HOST=mysql (as mysql is the creative name of the MySQL container).

Then run:

docker-compose build
docker-compose up

Use Docker directly to run with your own database

Use this process if you're a developer and want complete control over your Monica container.

Edit .env again to set the DB_* variables to match your database. Then run:

docker build -t monicahq/monicahq .
docker run --env-file .env -p 80:80 monicahq/monicahq    # to run MonicaHQ
# ...or...
docker run --env-file .env -it monicahq/monicahq shell   # to get a prompt

Note that uploaded files, like avatars, will disappear when you restart the container. Map a volume to /var/www/monica/storage/app/public if you want that data to persist between runs. See docker-compose.yml for examples.
