Hello everyone, I'm trying to set a docker environnement containing an instance of Gitlab + JupyterHub.
As a starting point, I use that example: https://github.com/jupyterhub/jupyterhub-deploy-docker It works like a charm with GitHub OAuth. I then switch to GitLab OAuth and works by using an gitlab.com account. So I moved on update the GITLAB_HOST variable in the JupyterHub image to use the docker image gitlab locally. And there is the strange behavior, if I set GITLAB_HOST with the local IP address of the server exposing port 80 and 443. I can connect to JupyterHub and launch notebooks using Gitlab account. But if I set the domain, it fails (error 500) the log of JupyterHub being: [I 2017-12-17 18:50:01.384 JupyterHub oauth2:82] OAuth redirect: 'http://jupyterhub.example.com/hub/oauth_callback' [I 2017-12-17 18:50:01.386 JupyterHub log:122] 302 GET /hub/oauth_login?next = → http://gitlab.example.com/oauth/authorize?client_id=...&state=...&response_type=code&redirect_uri=http%3A%2F%2Fjupyterhub.example.com%2Fhub%2Foauth_callback (@192.168.1.60) 2.51ms [E 2017-12-17 18:50:01.616 JupyterHub web:1590] Uncaught exception GET /hub/ oauth_callback?code=..&state=...

(@192.168.1.60) 20.01ms I'm not familiar with networks and docker. But if you could point me to a solution or a way to get more useful information to figure out the source of the error, I would appreciate. Kindly Frederic For info the docker-compose.yml looks like that: version: "2" services: web: image: 'gitlab/gitlab-ce:latest' restart: always container_name: gitlab environment: GITLAB_OMNIBUS_CONFIG: | external_url 'http://gitlab.example.com' unicorn['worker_processes'] = 2 nginx['custom_nginx_config'] = "include /var/opt/gitlab/nginx/conf.d/jupyterhub-http.conf;" ports: - '80:80' - '443:443' volumes: - '/srv/gitlab/config:/etc/gitlab' - '/srv/gitlab/logs:/var/log/gitlab' - '/srv/gitlab/data:/var/opt/gitlab' hub-db: image: postgres:9.5 container_name: jupyterhub-db restart: always environment: POSTGRES_DB: ${POSTGRES_DB} PGDATA: ${DB_VOLUME_CONTAINER} env_file: - secrets/postgres.env volumes: - "db:${DB_VOLUME_CONTAINER}" hub: depends_on: - hub-db build: context: . dockerfile: Dockerfile.jupyterhub args: JUPYTERHUB_VERSION: ${JUPYTERHUB_VERSION} restart: always image: jupyterhub container_name: jupyterhub volumes: - "/var/run/docker.sock:/var/run/docker.sock:rw" - "data:${DATA_VOLUME_CONTAINER}" links: - hub-db environment: DOCKER_NETWORK_NAME: ${DOCKER_NETWORK_NAME} DOCKER_NOTEBOOK_IMAGE: ${LOCAL_NOTEBOOK_IMAGE} DOCKER_NOTEBOOK_DIR: ${DOCKER_NOTEBOOK_DIR} DOCKER_SPAWN_CMD: ${DOCKER_SPAWN_CMD} POSTGRES_DB: ${POSTGRES_DB} POSTGRES_HOST: hub-db env_file: - secrets/postgres.env - secrets/oauth.env command: > jupyterhub -f /srv/jupyterhub/jupyterhub_config.py volumes: data: external: name: ${DATA_VOLUME_HOST} db: external: name: ${DB_VOLUME_HOST} networks: default: external: name: ${DOCKER_NETWORK_NAME} -- You received this message because you are subscribed to the Google Groups "Project Jupyter" group.
