# Create demo categories for OpenStack: Virtual Private Cloud, VMs and Storage
docker exec -t waldur-mastermind-worker waldur load_categories vpc vm storage

Waldur HomePort will be accessible on https://localhost. API will listen on https://localhost/api.

Healthcheck can be accessed on https://localhost/health-check.

Tearing down and cleaning up:

1
docker compose down

Logs

Logs emitted by the containers are collected and saved in the waldur_logs folder. You can change the location by editing environment variable (.env) and updating LOG_FOLDER value.

Known issues

When Waldur is launched for the first time, it applies initial database migrations. It means that you may need to wait few minutes until these migrations are applied. Otherwise you may observe HTTP error 500 rendered by REST API server. This issue would be resolved after upgrade to Docker Compose 1.29.

To use a custom script offering type, it should be possible to connect to /var/run/docker.sock from within the Waldur containers. If you are getting a permission denied error in logs, try setting more open permissions, for example, chmod 666 /var/run/docker.sock. Note that this is not a secure setup, so make sure you understand what you are doing.

Upgrade Instructions for PostgreSQL Images

Upgrade Script

To simplify the upgrade process, an upgrade script db-upgrade-script.sh is included in the root directory, and can be used to automate the upgrade process.

Usage Instructions

  1. Ensure the script has execution permissions:

bash chmod +x db-upgrade-script.sh

  1. Update the WALDUR_POSTGRES_IMAGE_TAG and KEYCLOAK_POSTGRES_IMAGE_TAG in the .env file to the desired versions.:

    1
2
    WALDUR_POSTGRES_IMAGE_TAG=<your_version>
KEYCLOAK_POSTGRES_IMAGE_TAG=<your_version>

  2. Run the sript:

bash ./db-upgrade-script.sh

Upgrade Prerequisites

  • Backup existing data (if needed).

Backup Commands

You can back up the database using pg_dumpall.

For Waldur DB:

1
docker exec -it waldur-db pg_dumpall -U waldur > /path/to/backup/waldur_upgrade_backup.sql

For Keycloak DB:

1
docker exec -it keycloak-db pg_dumpall -U keycloak > /path/to/backup/keycloak_upgrade_backup.sql

Shut down containers:

1
docker compose down

Note: Before upgrading PostgreSQL, please delete the pgsql folder within the project directory if it exists, as well as the keycloak_db docker volume if it exists. These were created with the previous PostgreSQL version, and they will be recreated with docker compose during upgrade.

You can remove the pgsql folder by running:

1
sudo rm -r pgsql/

To remove the keycloak_db volume, run:

1
 docker volume rm waldur-docker-compose_keycloak_db

Warning: This action will delete your existing PostgreSQL data. Ensure it is backed up before proceeding.

Upgrade Steps

  1. Update PostgreSQL Versions

    Update the WALDUR_POSTGRES_IMAGE_TAG and KEYCLOAK_POSTGRES_IMAGE_TAG in the .env file to the required versions.

    1
2
    WALDUR_POSTGRES_IMAGE_TAG=<your_version>
KEYCLOAK_POSTGRES_IMAGE_TAG=<your_version>

  2. Pull the New Images

    Pull the new PostgreSQL images:

    1
    docker compose pull

  3. Optional: Restore Data (if backups have been made)

    Start the database containers to load the dump data:

    1
    docker compose up -d waldur-db keycloak-db

    Restore the contents of the database from the dump file:

    For Waldur DB:

    1
    cat waldur_upgrade_backup.sql | docker exec -i waldur-db psql -U waldur

    For Keycloak DB:

    1
    cat keycloak_upgrade_backup.sql | docker exec -i keycloak-db psql -U keycloak

    Post-update steps

    If the new psql version is later than 14, you need to create SCRAM tokens for the existing users. For this, run the following lines, which will automatically create necessary tokens for the users.

    1

3
4
    export $(cat .env | grep "^POSTGRESQL_PASSWORD=" | xargs)
docker exec -it waldur-db psql -U waldur -c "ALTER USER waldur WITH PASSWORD '${POSTGRESQL_PASSWORD}';"
export $(cat .env | grep "^KEYCLOAK_POSTGRESQL_PASSWORD=" | xargs)
docker exec -it keycloak-db psql -U keycloak -c "ALTER USER keycloak WITH PASSWORD '${KEYCLOAK_POSTGRESQL_PASSWORD}';"

  4. Start containers

    Start all of the containers:

    1
    docker compose up -d

  5. Verify the Upgrade

    Verify the containers are running with the new PostgreSQL version:

    1
    docker ps -a

    Check container logs for errors:

    1
2
    docker logs waldur-db
docker logs keycloak-db

Using TLS

This setup supports following types of SSL certificates:

  • Email - set environment variable TLS to your email to register Let's Encrypt account and get free automatic SSL certificates.

Example:

1
TLS=my@email.com
  • Internal - set environment variable TLS to "internal" to generate self-signed certificates for dev environments

Example:

1
TLS=internal
  • Custom - set environment variable TLS to "cert.pem key.pem" where cert.pem and key.pem - are paths to your custom certificates (this needs modifying docker-compose with path to your certificates passed as volumes)

Example:

1
TLS=cert.pem key.pem

Custom Caddy configuration files

To add additional caddy config snippets into the caddy virtual host configuration add .conf files to config/caddy-includes/

Keycloak

Keycloak is an Identity and Access Management software bundled with waldur-docker-compose.

To create a keycloak admin account set KEYCLOAK_ADMIN env variable in docker-compose.yaml and KEYCLOAK_ADMIN_PASSWORD in .env file.

After this, you can login to the admin interface at https://localhost/auth/admin and create Waldur users.

To use Keycloak as an identity provider within Waldur, follow the instruction here. The discovery url to connect to Keycloak from the waldur-mastermind-api container is:

1
http://keycloak:8080/auth/realms/<YOUR REALM>/.well-known/openid-configuration

Integration with SLURM

The integration is described here.

Whitelabeling settings

To set up whitelabeling, you need to define settings in ./config/waldur-mastermind/whitelabeling.yaml. You can see the list of all whitelabeling options below.

General whitelabeling settings

  • site_name
  • site_address
  • site_email
  • site_phone
  • short_page_title

Logos and images of whitelabeling

The path to a logo is constructed like so: /etc/waldur/icons - is a path in the container (Keep it like it is) + the name of the logo file from config/whitelabeling directory.

All-together /etc/waldur/icons/file_name_from_whitelabeling_directory

  • powered_by_logo
  • hero_image
  • sidebar_logo
  • sidebar_logo_mobile
  • site_logo
  • login_logo
