Basic usage

1. Set up Docker Swarm and abra
2. Deploy coop-cloud/traefik
3. abra app new ${REPO_NAME}
   • WARNING: Choose "n" when abra asks if you'd like to generate secrets
4. abra app config YOURAPPNAME - be sure to change $DOMAIN to something that resolves to your Docker swarm box
5. Insert secrets:
   • abra app secret insert YOURAPPNAME secret_key v1 $(openssl rand -hex 32) #12
   • abra app secret generate -a YOURAPPNAME
6. abra app deploy YOURAPPNAME
7. Open the configured domain in your browser to finish set-up

Tips & Tricks

Create an initial admin user

abra app cmd YOURAPPNAME app create_email_user test@example.com

Setting up your .env config

Avoid the use of quotes ("...") as much as possible, the NodeJS scripts flip out for some reason on some vars.

Deleting a user (e.g. to fix SSO weirdness)

abra app cmd YOURAPPNAME db delete_user <username-to-delete> <username-to-replace>

Where <username-to-delete> is the username of the user to be removed, and <username-to-replace> is the username of another user, to assign documents and revisions to (instead of deleting them).

Migrate from S3 to local storage

• abra app config <domain>, add
  • COMPOSE_FILE="$COMPOSE_FILE:compose.local.yml"
  • FILE_STORAGE_UPLOAD_MAX_SIZE=26214400
• abra app deploy <domain> -f
  • compose.aws.yml should still be deployed!
• abra app undeploy <domain>
• on the docker host, find mountpoint of newly created volume via docker volume ls and docker volume inspect
  • volume name is smth like <domain>_storage-data
• take note which linux user owns <storage_mountpoint> (likely 1001)
• use s3cmd/rclone/... to sync your bucket to <storage_mountpoint>
• chown -R <storage_user>:<storage_user> <storage_mountpoint>
• abra app config <domain>, switch storage backend
  • remove AWS_* vars, SECRET_AWS_SECRET_KEY_VERSION and COMPOSE_FILE="$COMPOSE_FILE:compose.aws.yml"
  • set FILE_STORAGE=local
• abra app deploy <domain> -f
• enjoy getting rid of S3 🥳

Single Sign On with Keycloak/Authentik

• Create an OIDC client in Keycloak (in Authentik this is called a provider and application)
• Run abra app config YOURAPPNAME, then uncomment everything in the OIDC_ section.
  • Valid Redirect URIs: https://YOURAPPDOMAIN/auth/oidc.callback
  • Reference the client/provider info to populate the _AUTH_URI _TOKEN_URI and _USERINFO_URI values
• Set the OIDC secret using the value from the client/provider abra app secret insert YOURAPPNAME oidc_client_secret v1 SECRETVALUE
• abra app deploy YOURAPPDOMAIN
