This installation method is for test-setups and small-scale production setups.
- A host with at least 2 CPU cores and 2 GB of RAM
- Docker Compose (Compose v2 is recommended, see here for instructions on how to upgrade)
To download the latest
docker-compose.yml open your terminal and navigate to the directory of your choice.
Run the following command:
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
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
# SMTP Host Emails are sent to
# Optionally authenticate (don't add quotation marks to your password)
# Use StartTLS
# Use SSL
# Email address authentik will send from, should have a correct @domain
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
See Configuration to change the internal ports. Be sure to run
docker compose up -d to rebuild with the new port numbers.
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, the time shown is localized.
Do not update or mount
/etc/localtime in the authentik containers.
This will not give any advantages. It will cause problems with OAuth and SAML authentication, e.g. see this GitHub issue.
Afterwards, run these commands to finish:
docker compose pull
docker compose up -d
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.
To start the initial setup, navigate to
http://<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).
An explanation about what each service in the docker compose file does, see Architecture.
