title: Docker Compose installation
|
|
---
|
|
|
|
This installation method is for test-setups and small-scale production setups.
|
|
|
|
:::info
|
|
You can also [view a video walk-through](https://www.youtube.com/watch?v=O1qUbrk4Yc8) of the installation process on Docker (with bonus details about email configuration and other important options).
|
|
:::
|
|
|
|
## Requirements
|
|
|
|
- A host with at least 2 CPU cores and 2 GB of RAM
|
|
- Docker
|
|
- Docker Compose
|
|
|
|
## Preparation
|
|
|
|
To download the latest `docker-compose.yml` open your terminal and navigate to the directory of your choice.
|
|
Run the following command:
|
|
|
|
```shell
|
|
wget https://goauthentik.io/docker-compose.yml
|
|
```
|
|
|
|
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:
|
|
|
|
```shell
|
|
# 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:
|
|
|
|
```shell
|
|
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:
|
|
|
|
```shell
|
|
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](../flow/stages/email/) to send verification/recovery emails.
|
|
|
|
To configure email credentials, append this block to your `.env` file
|
|
|
|
```shell
|
|
# 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`:
|
|
|
|
```shell
|
|
COMPOSE_PORT_HTTP=80
|
|
COMPOSE_PORT_HTTPS=443
|
|
```
|
|
|
|
See [Configuration](../installation/configuration) to change the internal ports. Be sure to run `docker-compose up -d` to rebuild with the new port numbers.
|
|
|
|
## Startup
|
|
|
|
:::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, the time shown is localized.
|
|
Do not update or mount `/etc/timezone` or `/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](https://github.com/goauthentik/authentik/issues/3005).
|
|
:::
|
|
|
|
Afterwards, run these commands to finish:
|
|
|
|
```shell
|
|
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](../releases).
|
|
|
|
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).
