| Docker Compose installation |
This installation method is for test-setups and small-scale production setups.
Requirements
- A host with at least 2 CPU cores and 2 GB of RAM
- Docker
- Docker Compose
Preparation
Download the latest docker-compose.yml from here. Place it in a directory of your choice.
If this is a fresh authentik installation, you need to generate a password and a secret key. If you don't already have a password generator installed, you can run this command to install pwgen, a popular generator:
# You can also use openssl instead: `openssl rand -base64 36`
sudo apt-get install -y pwgen
Next, run the following commands to generate a password and secret key and write them to your .env file:
echo "PG_PASS=$(pwgen -s 40 1)" >> .env
echo "AUTHENTIK_SECRET_KEY=$(pwgen -s 50 1)" >> .env
# Because of a PostgreSQL limitation, only passwords up to 99 chars are supported
# See https://www.postgresql.org/message-id/09512C4F-8CB9-4021-B455-EF4C4F0D55A0@amazon.com
To enable error reporting, run the following command:
echo "AUTHENTIK_ERROR_REPORTING__ENABLED=true" >> .env
Email configuration (optional but recommended)
It is also recommended to configure global email credentials. These are used by authentik to notify you about alerts and configuration issues. They can also be used by Email stages to send verification/recovery emails.
To configure email credentials, append this block to your .env file
# SMTP Host Emails are sent to
AUTHENTIK_EMAIL__HOST=localhost
AUTHENTIK_EMAIL__PORT=25
# Optionally authenticate (don't add quotation marks to your password)
AUTHENTIK_EMAIL__USERNAME=
AUTHENTIK_EMAIL__PASSWORD=
# Use StartTLS
AUTHENTIK_EMAIL__USE_TLS=false
# Use SSL
AUTHENTIK_EMAIL__USE_SSL=false
AUTHENTIK_EMAIL__TIMEOUT=10
# Email address authentik will send from, should have a correct @domain
AUTHENTIK_EMAIL__FROM=authentik@localhost
Configure for port 80/443
By default, authentik listens internally on port 9000 for HTTP and 9443 for HTTPS. To change the exposed ports to 80 and 443, you can set the following variables in .env:
COMPOSE_PORT_HTTP=80
COMPOSE_PORT_HTTPS=443
See Configuration to change the internal ports. Be sure to run docker-compose up -d to rebuild with the new port numbers.
Startup
Afterwards, run these commands to finish:
docker-compose pull
docker-compose up -d
The docker-compose.yml file statically references the latest version available at the time of downloading the compose file. Each time you upgrade to a newer version of authentik, you download a new docker-compose.yml file, which points to the latest available version. For more information, refer to the Upgrading section in the Release Notes.
By default, authentik is reachable (by default) on port 9000 (HTTP) and port 9443 (HTTPS).
To start the initial setup, navigate to https://<your server's IP or hostname>:9000/if/flow/initial-setup/.
There you are prompted to set a password for the akadmin user (the default user).
Explanation
:::warning
The server assumes to have local timezone as UTC.
All internals are handled in UTC; whenever a time is displayed to the user in UI it gets localized.
Do not update or mount /etc/timezone or /etc/localtime in the authentik containers.
This will not give any advantages.
On the contrary, it will cause problems with OAuth and SAML authentication,
e.g. see this GitHub issue.
:::
The Docker-Compose project contains the following containers:
-
server
This is the backend service, which does all the logic, plus runs the API and the SSO functionality. It also runs the frontend, hosts the JS/CSS files, and serves the files you've uploaded for icons/etc.
-
worker
This container executes background tasks, everything you can see on the System Tasks page in the frontend.
-
redis (for cache)
-
postgresql (default database)
