Hi JupyterHub community, I am trying to deploy JupyterHub with DockerSpawner to a fresh Ubuntu 22 LTS VM, however I am running into problems. **Can someone give me a pointer to how I may debug this? Should I file an issue with the jupyterhub Github repo, or might it be an issue with my administration?** **Expected Behavior:** After installation, I can signup and login with the admin account **Actual Behavior:** When logging in, I get a 302 redirect back to the login screen and no JupyterLab environment is created using DockerSpawner. Steps taken: **1. Create a fresh Ubuntu 22 LTS VM on Digital Ocean and login** ```auto ssh xxx.xxx.xxx.xxx ``` **2. Run `install-docker.sh`** ```auto #!/bin/bash # Instructions from https://docs.docker.com/engine/install/ubuntu/ sudo apt-get update sudo apt-get install -y ca-certificates curl gnupg sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-compose ``` **3. Clone the official `jupyterhub-deploy-docker` repo** ```auto git clone https://github.com/jupyterhub/jupyterhub-deploy-docker.git ``` **4. Build and run the Docker image per the `README.md`** ```auto cd jupyterhub-deploy-docker/basic-example docker-compose build docker-compose up ``` **5. Navigate to JupyterHub in my web browser and attempt the signup + login workflow** First, I navigate to the JupyterHub server. Next, I click “sign up”. I sign up with either username/password of admin/password or toby/password. Then, I go back to the login screen. Next, I login with one of the username/password combos. Finally, I get redirected straight back to the login screen with a 302 HTTP response. So, I cannot get to JupyterLab ☹ The content of the JupyterHub Docker container logs from startup to redirect are below: ```auto root@indieagi-jupyterhub-droplet:~/jupyterhub-deploy-docker/basic-example# docker-compose up Creating network "jupyterhub-network" with the default driver Creating volume "basic-example_jupyterhub-data" with default driver Creating jupyterhub ... done Attaching to jupyterhub jupyterhub | [I 2023-08-24 23:53:27.988 JupyterHub app:2859] Running JupyterHub version 4.0.2 jupyterhub | [I 2023-08-24 23:53:27.989 JupyterHub app:2889] Using Authenticator: nativeauthenticator.nativeauthenticator.NativeAuthenticator jupyterhub | [I 2023-08-24 23:53:27.989 JupyterHub app:2889] Using Spawner: dockerspawner.dockerspawner.DockerSpawner-12.1.0 jupyterhub | [I 2023-08-24 23:53:27.989 JupyterHub app:2889] Using Proxy: jupyterhub.proxy.ConfigurableHTTPProxy-4.0.2 jupyterhub | [I 2023-08-24 23:53:28.005 JupyterHub app:1709] Writing cookie_secret to /data/jupyterhub_cookie_secret jupyterhub | [I 2023-08-24 23:53:28.048 alembic.runtime.migration migration:213] Context impl SQLiteImpl. jupyterhub | [I 2023-08-24 23:53:28.048 alembic.runtime.migration migration:216] Will assume non-transactional DDL. jupyterhub | [I 2023-08-24 23:53:28.063 alembic.runtime.migration migration:621] Running stamp_revision -> 0eee8c825d24 jupyterhub | [I 2023-08-24 23:53:28.330 JupyterHub proxy:556] Generating new CONFIGPROXY_AUTH_TOKEN jupyterhub | [W 2023-08-24 23:53:28.366 JupyterHub auth:37] jupyterhub | The shared database session at Authenticator.db is deprecated, and will be removed. jupyterhub | Please manage your own database and connections. jupyterhub | jupyterhub | Contact JupyterHub at https://github.com/jupyterhub/jupyterhub/issues/3700 jupyterhub | if you have questions or ideas about direct database needs for your Authenticator. jupyterhub | jupyterhub | [I 2023-08-24 23:53:28.377 JupyterHub roles:238] Adding role admin for User: admin jupyterhub | [I 2023-08-24 23:53:28.386 JupyterHub roles:238] Adding role user for User: admin jupyterhub | [I 2023-08-24 23:53:28.392 JupyterHub app:1984] Not using allowed_users.

You might check your content or tracker prevention settings in your browser, because it seems like something is blocking the jupyterhub login cookie. Perhaps the browser console will shed some light. Maybe try in a private window or other browser. These are the logs I get from running your steps: > **** > > ```auto > jupyterhub | [I 2023-08-28 07:10:35.738 JupyterHub app:2859] Running JupyterHub version 4.0.2 > jupyterhub | [I 2023-08-28 07:10:35.738 JupyterHub app:2889] Using Authenticator: nativeauthenticator.nativeauthenticator.NativeAuthenticator > jupyterhub | [I 2023-08-28 07:10:35.738 JupyterHub app:2889] Using Spawner: dockerspawner.dockerspawner.DockerSpawner-12.1.0 > jupyterhub | [I 2023-08-28 07:10:35.738 JupyterHub app:2889] Using Proxy: jupyterhub.proxy.ConfigurableHTTPProxy-4.0.2 > jupyterhub | [I 2023-08-28 07:10:35.760 JupyterHub app:1709] Writing cookie_secret to /data/jupyterhub_cookie_secret > jupyterhub | [I 2023-08-28 07:10:35.794 alembic.runtime.migration migration:213] Context impl SQLiteImpl. > jupyterhub | [I 2023-08-28 07:10:35.794 alembic.runtime.migration migration:216] Will assume non-transactional DDL. > jupyterhub | [I 2023-08-28 07:10:35.803 alembic.runtime.migration migration:621] Running stamp_revision -> 0eee8c825d24 > jupyterhub | [I 2023-08-28 07:10:35.946 JupyterHub proxy:556] Generating new CONFIGPROXY_AUTH_TOKEN > jupyterhub | [W 2023-08-28 07:10:35.961 JupyterHub auth:37] > jupyterhub | The shared database session at Authenticator.db is deprecated, and will be removed. > jupyterhub | Please manage your own database and connections. > jupyterhub | > jupyterhub | Contact JupyterHub at https://github.com/jupyterhub/jupyterhub/issues/3700 > jupyterhub | if you have questions or ideas about direct database needs for your Authenticator. > jupyterhub | > jupyterhub | [I 2023-08-28 07:10:35.965 JupyterHub roles:238] Adding role admin for User: admin > jupyterhub | [I 2023-08-28 07:10:35.971 JupyterHub roles:238] Adding role user for User: admin > jupyterhub | [I 2023-08-28 07:10:35.975 JupyterHub app:1984] Not using allowed_users.

> This suggests to me that the login cookie set by `/hub/login` is not being sent in the subsequent request to `/hub/spawn` , either because it’s not set correctly or something is preventing it from being set and/or sent. @minrk I believe you may be correct. I had two further observations today: 1. I think we forgot to configure SSL on this instance 2. The login works if we use the IP address of JupyterHub to access the login screen instead of its DNS record Will be prioritizing this soon and can update with the resolution. ---

The issue was SSL configuration. To fix the issue, a friend changed the `docker-compose.yml` with the following patch. I’m unsure the patch is production-quality, but I’m open to feedback. ```auto diff --git a/runtime-config/docker-compose.yml b/runtime-config/docker-compose.yml index 111184a..17a8b16 100644 --- a/runtime-config/docker-compose.yml +++ b/runtime-config/docker-compose.yml @@ -24,8 +24,6 @@ services: - "/var/run/docker.sock:/var/run/docker.sock:rw" # Bind Docker volume on host for JupyterHub database and cookie secrets - "jupyterhub-data:/data" - ports: - - "8000:8000" environment: # This username will be a JupyterHub admin JUPYTERHUB_ADMIN: admin @@ -37,6 +35,37 @@ services: DOCKER_NOTEBOOK_DIR: /home/jovyan/work # Using this run command DOCKER_SPAWN_CMD: start-singleuser.sh + labels: + - "traefik.enable=true" + # Put domain to host on between the backticks + - "traefik.http.routers.jupyterhub.rule=Host(`jupyter-dev.indieagi.org`)" + - "traefik.http.services.jupyterhub.loadbalancer.server.port=8000" + - "traefik.http.routers.jupyterhub.tls=true" + - "traefik.http.routers.jupyterhub.tls.certresolver=myresolver" + + + traefik: + image: "traefik:v2.10" + container_name: "traefik" + command: + - "--providers.docker=true" + - "--providers.docker.exposedbydefault=false" + - "--entrypoints.web.address=:80" + - "--entrypoints.websecure.address=:443" + - "--certificatesresolvers.myresolver.acme.storage=/etc/traefik/acme/acme.json" + # Put email here for Let's Encrypt + - "--certificatesresolvers.myresolver.acme.email=test@jupyter-dev.indieagi.org" + - "--certificatesresolvers.myresolver.acme.httpchallenge.entrypoint=web" + networks: + - jupyterhub-network + ports: + - "80:80" + - "443:443" + volumes: + - "/var/run/docker.sock:/var/run/docker.sock:ro" + - "./acme:/etc/traefik/acme" # Map acme.json to a host directory + + volumes: jupyterhub-data: ```
