title: docker-compose installation
|
|
---
|
|
|
|
This installation method is for test-setups and small-scale productive setups.
|
|
|
|
## Requirements
|
|
|
|
- A Linux host with at least 2 CPU cores and 2 GB of RAM.
|
|
- docker
|
|
- docker-compose
|
|
|
|
## Preparation
|
|
|
|
Download the latest `docker-compose.yml` from [here](https://raw.githubusercontent.com/goauthentik/authentik/version/2021.9.1-rc2/docker-compose.yml). Place it in a directory of your choice.
|
|
|
|
To optionally deploy a different version run `echo AUTHENTIK_TAG=2021.9.1-rc2 >> .env`
|
|
|
|
If this is a fresh authentik install run the following commands to generate a password:
|
|
|
|
```shell
|
|
# You can also use openssl instead: `openssl rand -base64 36`
|
|
sudo apt-get install -y pwgen
|
|
# 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
|
|
echo "PG_PASS=$(pwgen 40 1)" >> .env
|
|
echo "AUTHENTIK_SECRET_KEY=$(pwgen 50 1)" >> .env
|
|
# Skip if you don't want to enable error reporting
|
|
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, configuration issues. They can also be used by [Email stages](flow/stages/email/index.md) to send verification/recovery emails.
|
|
|
|
Append this block to your `.env` file
|
|
|
|
```shell
|
|
# SMTP Host Emails are sent to
|
|
AUTHENTIK_EMAIL__HOST=localhost
|
|
AUTHENTIK_EMAIL__PORT=25
|
|
# Optionally authenticate
|
|
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
|
|
```
|
|
|
|
## GeoIP configuration (optional)
|
|
|
|
authentik can use a MaxMind-formatted GeoIP Database to extract location data from IPs. You can then use this location data in policies, and location data is saved in events.
|
|
|
|
To configure GeoIP, sign up for a free MaxMind account [here](https://www.maxmind.com/en/geolite2/signup).
|
|
|
|
After you have your account ID and license key, add the following block to your `.env` file:
|
|
|
|
```shell
|
|
GEOIPUPDATE_ACCOUNT_ID=*your account ID*
|
|
GEOIPUPDATE_LICENSE_KEY=* your license key*
|
|
AUTHENTIK_AUTHENTIK__GEOIP=/geoip/GeoLite2-City.mmdb
|
|
```
|
|
|
|
The GeoIP database will automatically be updated every 8 hours.
|
|
|
|
## Startup
|
|
|
|
Afterwards, run these commands to finish
|
|
|
|
```shell
|
|
docker-compose pull
|
|
docker-compose up -d
|
|
```
|
|
|
|
The compose file statically references the latest version available at the time of downloading the compose file, which can be overridden with the `AUTHENTIK_TAG` environment variable.
|
|
|
|
authentik will then be reachable on port 9000 (HTTP) and port 9443 (HTTPS).
|
|
|
|
To start the initial setup, navigate to `https://<your server>/if/flow/initial-setup/`. There you will be prompted to set a password for the akadmin user.
|
|
|
|
## Explanation
|
|
|
|
The docker-compose project contains the following containers:
|
|
|
|
- server
|
|
|
|
This is the backend service, which does all the logic, runs the API and the actual SSO part. It also runs the frontend, hosts the JS/CSS files, and also servers 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 & postgresql
|
|
|
|
Cache and database respectively.
|
|
|
|
Additionally, if you've enabled GeoIP, there is a container running that regularly updates the GeoIP database.
