Docker Installation

note

Mbin is still in development.

System Requirements​

  • Docker Engine

  • Docker Compose V2

    If you are using Compose V1, replace docker compose with docker-compose in those commands below.

Docker Install​

The most convenient way to install docker is using an official convenience script provided at get.docker.com:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

Alternatively, you can follow the official Docker install documentation for your platform.

Once Docker is installed on your system, it is recommended to create a docker group and add it to your user:

sudo groupadd docker
sudo usermod -aG docker $USER

Mbin Installation​

Preparation​

Clone git repository:

git clone https://github.com/MbinOrg/mbin.git
cd mbin

Docker image preparation​

note

If you're using a version of Docker Engine earlier than 23.0, run export DOCKER_BUILDKIT=1, prior to building the image. This does not apply to users running Docker Desktop. More info can be found here

  1. First go to the docker directory:
cd docker
  1. Use the existing Docker image OR build the docker image. Select one of the two options.

Build our own Docker image​

If you want to build our own image, run (no need to update the compose.yml file):

docker build --no-cache -t mbin -f Dockerfile  ..

Use Mbin pre-build image​

OR use our pre-build images from ghcr.io. In this case you need to update the compose.yml file:

nano compose.yml

Find and replace or comment-out the following 4 lines:

build:
  context: ../
  dockerfile: docker/Dockerfile
image: mbin

And instead use the following line on all places (www, php, and messenger services):

image: "ghcr.io/mbinorg/mbin:latest"

Important: Do NOT forget to change ALL LINES in that matches image: mbin to: image: "ghcr.io/mbinorg/mbin:latest" in the compose.yml file (should be 4 matches in total).

  1. Create config files and storage directories:
cp ../.env.example_docker .env
cp compose.prod.yml compose.override.yml
mkdir -p storage/media storage/caddy_config storage/caddy_data storage/logs
sudo chown $USER:$USER storage/media storage/caddy_config storage/caddy_data storage/logs

Configure .env and compose.override.yml​

  1. Choose your Redis password, PostgreSQL password, RabbitMQ password, and Mercure password.
  2. Place the passwords in the corresponding variables in both .env and compose.override.yml.
  3. Update the SERVER_NAME, KBIN_DOMAIN and KBIN_STORAGE_URL in .env.
  4. Update APP_SECRET in .env, generate a new one via: node -e "console.log(require('crypto').randomBytes(16).toString('hex'))"
  5. Optionally: Use a newer PostgreSQL version (current fallback is v13). Update/set the POSTGRES_VERSION variable in your .env and compose.override.yml under db.
note

Ensure the HTTPS environmental variable is set to TRUE in compose.override.yml for the php, messenger, and messenger_ap containers if your environment is using a valid certificate behind a reverse proxy. This is likely true for most production environments and is required for proper federation, that is, this will ensure the webfinger responses include https: in the URLs generated.

Configure OAuth2 keys​

  1. Create an RSA key pair using OpenSSL:
# Replace <mbin_dir> with Mbin's root directory
mkdir <mbin_dir>/config/oauth2/
# If you protect the key with a passphrase, make sure to remember it!
# You will need it later
openssl genrsa -des3 -out ./config/oauth2/private.pem 4096
openssl rsa -in ./config/oauth2/private.pem --outform PEM -pubout -out ./config/oauth2/public.pem
  1. Generate a random hex string for the OAuth2 encryption key:
openssl rand -hex 16
  1. Add the public and private key paths to .env:
OAUTH_PRIVATE_KEY=%kernel.project_dir%/config/oauth2/private.pem
OAUTH_PUBLIC_KEY=%kernel.project_dir%/config/oauth2/public.pem
OAUTH_PASSPHRASE=<Your (optional) passphrase from above here>
OAUTH_ENCRYPTION_KEY=<Hex string generated in previous step>

Running the containers​

By default docker compose will execute the compose.yml and compose.override.yml files.

Run the container in the background (-d means detach, but this can also be omitted for testing or debugging purposes):

# Go to the docker directory within the git repo
cd docker

# Starts the containers
docker compose up -d

See your running containers via: docker ps.

Then, you should be able to access the new instance via http://localhost:8008. You can also access RabbitMQ management UI via http://localhost:15672.

Add auxiliary containers to compose.yml​

Add any auxiliary container as you want. For example, add a Nginx container as reverse proxy to provide HTTPS encryption.

note

If you are building the docker images yourself, you might get merge conflicts when changing the compose.yml

Uploaded media files​

Uploaded media files (e.g. photos uploaded by users) will be stored on the host directory storage/media. They will be served by the Caddy web server in the www container as static files.

Make sure KBIN_STORAGE_URL in your .env configuration file is set to be https://yourdomain.tld/media (assuming you setup Nginx with SSL certificate by now).

You can also serve those media files on another server by mirroring the files at storage/media and changing KBIN_STORAGE_URL correspondingly.

Filesystem ACL support​

The filesystem ACL is disabled by default, in the mbin image. You can set the environment variable ENABLE_ACL=1 to enable it. Remember that not all filesystems support ACL. This will cause an error if you enable filesystem ACL for such filesystems.

Run Production​

If you created the file compose.override.yml with your configs (cp compose.prod.yml compose.override.yml), running production would be the same command:

docker compose up -d

Important: The docker instance is can be reached at http://127.0.0.1:8008, we strongly advise you to put a reverse proxy (like Nginx) in front of the docker instance. Nginx can could listen on ports 80 and 443 and Nginx should handle SSL/TLS offloading. See also Nginx example below.

If you want to deploy your app on a cluster of machines, you can use Docker Swarm, which is compatible with the provided Compose files.

Mbin NGINX Server Block​

NGINX reverse proxy example for the Mbin Docker instance:

# Redirect HTTP to HTTPS
server {
    server_name domain.tld;
    listen 80;

    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name domain.tld;

    charset utf-8;
