## Postgres Dockerfile ## Postgres Dockerfile
This example shows a Dockerfile that can be used to connect Jupyterhub to a Postgres backend.
### Running the Container This example shows how you can connect Jupyterhub to a Postgres database
0. Replace `ENV JPY_PSQL_PASSWORD arglebargle` with your own password in the Dockerfile. instead of the default SQLite backend.
### Running Postgres with Jupyterhub on the host.
0. Replace `ENV JPY_PSQL_PASSWORD arglebargle` with your own password in the
Dockerfile for `examples/postgres/db`. (Alternatively you can pass -e
`JPY_PSQL_PASSWORD=<password>` when you start the db container.)
1. `cd` to the root of your jupyterhub repo. 1. `cd` to the root of your jupyterhub repo.
2. Build the postgres image with `docker build -t jupyterhub-postgres examples/postgres_db/`. This may take some time the first time it's run.
3. Run the image with `docker run -d -p 5433:5432 jupyterhub-postgres`. This will start a postgres daemon container in the background that's listening on your localhost port 5433. 2. Build the postgres image with `docker build -t jupyterhub-postgres-db
4. Run jupyterhub with `jupyterhub--db=postgresql://jupyterhub:<password>@localhost:5433/jupyterhub`. examples/postgres/db`. This may take a minute or two the first time it's
run.
3. Run the db image with `docker run -d -p 5433:5432 jupyterhub-postgres`.
This will start a postgres daemon container in the background that's
listening on your localhost port 5433.
4. Run jupyterhub with
`jupyterhub--db=postgresql://jupyterhub:<password>@localhost:5433/jupyterhub`.
### Running Postgres with Containerized Jupyterhub.
0. Replace `ENV JPY_PSQL_PASSWORD arglebargle` with your own password in the
Dockerfile for `examples/postgres/hub`. (Alternatively you can pass -e
`JPY_PSQL_PASSWORD=<password>` when you start the hub container.)
1. Do steps 0-2 in from the above section, ensuring that the values set/passed
for `JPY_PSQL_PASSWORD` match for the hub and db containers.
2. Build the hub image with `docker build -t jupyterhub-postgres-db
examples/postgres/db`. This may take a minute or two the first time it's run.
3. Run the db image with `docker run -d --name=jpy-db
jupyterhub-postgres`. Note that, unlike when connecting to a host machine
jupyterhub, we don't specify a port-forwarding scheme here, but we do need
to specify a name for the container.
4. Run the containerized hub with `docker run -it --link jpy-db:postgres
jupyterhub-postgres-hub`.
