Images are based on Alpine, check tags below

• Alpine images are available for linux/amd64 and linux/arm64/v8 platform
• Weekly build are deployed to Docker hub on Sunday 4am (GMT+1)

Tags

bareos-director (dir)

• 21-alpine-pgsql, 21-alpine, alpine, latest
• 20-alpine-pgsql, 20-alpine

bareos-client (fd) - bareos-storage (sd) - bareos-webui

• 21-alpine, alpine, latest
• 20-alpine, latest

bareos-api

• 21-alpine, 21, alpine, latest

Setup

Bareos Director requires :

• PostgreSQL
• SMTP Daemon as mail router (for reporting)

Bareos Webui requires :

• PHP-FPM

Bareos Client (fd) and Storage (sd) have no dependencies.

Each component have to run in an single container and must linked together through docker-compose, see example below

Requirements

• Docker & docker-compose

Usage

Define ENV variables required

Declare environment variables or copy the .env.dist to .env and adjust its values.

Remember that all passwords should be defined inside this .env file. It's recommanded to not use default passwords in .env.dist for production usage.

Finaly, be sure to update variables in docker-compose file like ADMIN_MAIL or DB_USER

Run docker-compose

docker-compose -f /path/to/your/docker-compose.yml up -d

docker-compose files are available for Alpine and Ubuntu based stack:

file	compose	docker	latest build
alpine-v1/mysql	v3+	v1.13.0+
alpine-v2/mysql	v3.7+	v18.06.0+
ubuntu/mysql	v3+	v1.13.0+
ubuntu/pgsql	v3+	v1.13.0+

📁 Those docker-compose file are configured to store data inside /data/(bareos|mysql|pgsql)

Finally, when your containers are up and running access Bareos using WebUI, CLI or API

Access WebUI

Open http://your-docker-host:8080 in your web browser then sign-in

(user: admin / pass: <BAREOS_WEBUI_PASSWORD>)

Access bconsole

docker exec -it bareos-dir bconsole

Access API

(Required Bareos 20+ and Bareos named console)

Open http://your-docker-host:8000/docs in your web browser then click 'Authorize' to sign-in.

Or use curl as example below:

Get token: (should return json object with token inside)

curl -X 'POST' \
  'http://your-docker-host:8000/token' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -d 'grant_type=&username=admin&password=ThisIsMySecretUIp4ssw0rd&scope=&client_id=&client_secret='

As you can see it uses credentials of Bareos-webui admin user which is configure as a named console in Bareos-director.

Result:

{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTY0NzIxMDM3NX0.alKiLsgMrovKVX6fdcUqkhG_9lsJNiOBQ6X7ixyziGw",
  "token_type": "bearer"
}

Then, use this token for example to read all clients configuration (like in bconsole)

curl -X 'GET' \
  'http://your-docker-host:8000/configuration/clients?verbose=yes' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTY0NzIxMDM3NX0.alKiLsgMrovKVX6fdcUqkhG_9lsJNiOBQ6X7ixyziGw'

Should return a JSON file with all clients configuration.

Access metrics for Prometheus

Open http://your-docker-host:9625/metrics in your web browser to display metrics available.

Metrics should be scraped by Prometheus server.

Database migration (MySQL to PostgreSQL)

Since Bareos Version >= 21.0.0 the MySQL database backend is not shipped anymore. Therefore you need to use Bareos 20 to migrate an existing MySQL Bareos Catalog to PostgreSQL. To do so, upgrade to Bareos 20 first and then use this docker-compose file to backup (optional) the whole Bareos MySQL catalog and copy it into a new PostgreSQL catalog database.

If PostgreSQL database is empty or does not exist, it will be created.

⚠️ Don't forget .env file with passwords required!

PostgreSQL database upgrade

Compatibility

At this moment, latest Ubuntu based images are compliant with PostgreSQL 12 or less and Alpine ones with PostgreSQL 14. This is due to the version of pg_dump which is required to dump Bareos database.

Ubuntu images:

• Bareos v19 -> PostgreSQL v10 or less
• Bareos v20+ -> PostgreSQL v12 or less

Alpine images:

• Bareos v19 -> PostgreSQL v13 or less
• Bareos v20+ -> PostgreSQL v14 or less

Tool

The main idea here is to use postgresql-upgrade Docker image. It will create a new PostgreSQL instance and then use pg_upgrade tool to move all databases from the old instance to the new one.

To proceed, locate your PostgreSQL data folder, according our own docker compose files it could be /data/pgsql/data ! Then identify user used to init the instance. postgres ? pgsql ? root ?

Let's try an exemple with data source /data/pgsql/data and postgres as an admin user.

Finaly run:

docker run -t -i \
  -e PG_NEW=12 \
  -e PGUSER=postgres \
  -v /data/pgsql/data:/pg_old/data \
  -v /data/pgsql-new/data:/pg_new/data \
  barcus/postgresql-upgrade

After sucessful migration, use the new folder /data/pgsql-new/data and the PostgreSQL version related in your docker-compose file.
