01. Docker Installation

Official Installation Page: Authentik Docker Installation

Again as usual we will leverage Dockge to install Authentik on our Docker VM that we have created in our Proxmox Server. If you have not done this yet then please go to Docker VM Install. 

1. According to the documentation we can obtain the docker compose file with the following command

wget https://docs.goauthentik.io/compose.yml
Docker Compose File 
services:
  postgresql:
    env_file:
      - .env
    environment:
      POSTGRES_DB: ${PG_DB:-authentik}
      POSTGRES_PASSWORD: ${PG_PASS:?database password required}
      POSTGRES_USER: ${PG_USER:-authentik}
    healthcheck:
      interval: 30s
      retries: 5
      start_period: 20s
      test:
        - CMD-SHELL
        - pg_isready -d $${POSTGRES_DB} -U $${POSTGRES_USER}
      timeout: 5s
    image: docker.io/library/postgres:16-alpine
    restart: unless-stopped
    volumes:
      - ./database:/var/lib/postgresql/data
  server:
    command: server
    depends_on:
      postgresql:
        condition: service_healthy
    env_file:
      - .env
    environment:
      AUTHENTIK_POSTGRESQL__HOST: postgresql
      AUTHENTIK_POSTGRESQL__NAME: ${PG_DB:-authentik}
      AUTHENTIK_POSTGRESQL__PASSWORD: ${PG_PASS}
      AUTHENTIK_POSTGRESQL__USER: ${PG_USER:-authentik}
      AUTHENTIK_SECRET_KEY: ${AUTHENTIK_SECRET_KEY:?secret key required}
    image: ${AUTHENTIK_IMAGE:-ghcr.io/goauthentik/server}:${AUTHENTIK_TAG:-2026.5.2}
    ports:
      - ${COMPOSE_PORT_HTTP:-9000}:9000
      - ${COMPOSE_PORT_HTTPS:-9443}:9443
    restart: unless-stopped
    shm_size: 512mb
    volumes:
      - ./data:/data
      - ./custom-templates:/templates
  worker:
    command: worker
    depends_on:
      postgresql:
        condition: service_healthy
    env_file:
      - .env
    environment:
      AUTHENTIK_POSTGRESQL__HOST: postgresql
      AUTHENTIK_POSTGRESQL__NAME: ${PG_DB:-authentik}
      AUTHENTIK_POSTGRESQL__PASSWORD: ${PG_PASS}
      AUTHENTIK_POSTGRESQL__USER: ${PG_USER:-authentik}
      AUTHENTIK_SECRET_KEY: ${AUTHENTIK_SECRET_KEY:?secret key required}
    image: ${AUTHENTIK_IMAGE:-ghcr.io/goauthentik/server}:${AUTHENTIK_TAG:-2026.5.2}
    restart: unless-stopped
    shm_size: 512mb
    user: root
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data:/data
      - ./certs:/certs
      - ./custom-templates:/templates

 

2. We then grab this docker compose file and copy paste it into our Dockge container and change the followingfollowing.

Most

Iof the docker compose file can stay in tact but if you are like me and want to keep everythingall files for one project in one folder insteadthen ofyou usingshould remove the docker volumes.database Hence,volume weand adjustreplace it with ./database. 

3. Next is creating an environment file that serves the values requested in the compose file

PG_DB=databasenameofyourinstance
PG_PASS=passwordofyourinstance
PG_USER=usernameforyourinstance
AUTHENTIK_SECRET_KEY=yoursecretkey
AUTHENTIK_IMAGE=ghcr.io/goauthentik/server
AUTHENTIK_TAG=2026.5.2 # This the Authentik version
COMPOSE_PORT_HTTP=9001 
COMPOSE_PORT_HTTPS=9444
