Docker container with Apache reverse proxy for Service Catalog notebook product

This is a component of the Service Catalog notebook product. The provsioned product sits behind an AWS ALB which authenticates the user, adds an access token as a header, and forwards the traffic to the instance, under the URL:

https:<host-name>/<ec2-instance-id>

It's the job of this reverse proxy to:

  • validate the access token;
  • make sure the access token is for the user assigned to the EC2 instance;
  • store the access token in SSM Parameter Store for later use;
  • forward the traffic to the notebook

To run a Jupyter notebook with this reverse proxy:

export EC2_INSTANCE_ID=...
export NOTEBOOK_CONTAINER_NAME=jupyter
export NETWORK_NAME=proxy-net

docker network create --driver bridge ${NETWORK_NAME}

docker run -d -p 443:443 --name reverse-proxy \
--network ${NETWORK_NAME} \
--restart unless-stopped \
-e EC2_INSTANCE_ID=${EC2_INSTANCE_ID} \
-e NOTEBOOK_HOST=${NOTEBOOK_CONTAINER_NAME} \
-e AWS_REGION=us-east-1 \
-e SERVICE_CATALOG_PREFIX=service-catalog/synapse/cred \
-e SSM_PARAMETER_SUFFIX=oidc-accesstoken \
ghcr.io/sage-bionetworks/notebook-reverse-proxy-jupyter:latest

Then run the notebook on the same network. For example:

# this is just an example user name, though it's the one Service Catalog uses today:
export HOME=/home/ssm-user

# The following should be customized, e.g., with an up-to-date version
export DOCKER_IMAGE=quay.io/jupyter/base-notebook:python-3.11

mkdir $HOME/workdir
chmod 777 $HOME/workdir

docker run -d --name ${NOTEBOOK_CONTAINER_NAME} \
--restart unless-stopped \
-e DOCKER_STACKS_JUPYTER_CMD=notebook \
-v $HOME/workdir:/home/jovyan/workdir \
--network ${NETWORK_NAME} ${DOCKER_IMAGE} \
start-notebook.py --IdentityProvider.token='' --NotebookApp.base_url=/${EC2_INSTANCE_ID} \
--notebook-dir=/home/jovyan/workdir

To run an RStudio notebook with this reverse proxy:

export EC2_INSTANCE_ID=...
export NOTEBOOK_CONTAINER_NAME=rstudio
export NETWORK_NAME=proxy-net

docker network create --driver bridge ${NETWORK_NAME}

docker run -d -p 443:443 --name reverse-proxy \
--network ${NETWORK_NAME} \
--restart unless-stopped \
-e EC2_INSTANCE_ID=${EC2_INSTANCE_ID} \
-e NOTEBOOK_HOST=${NOTEBOOK_CONTAINER_NAME} \
-e AWS_REGION=us-east-1 \
-e SERVICE_CATALOG_PREFIX=service-catalog/synapse/cred \
-e SSM_PARAMETER_SUFFIX=oidc-accesstoken \
ghcr.io/sage-bionetworks/notebook-reverse-proxy-rstudio:latest

Then run the notebook on the same network. For example:

# this is just an example user name, though it's the one Service Catalog uses today:
export HOME=/home/ssm-user

# The following should be customized, e.g., with an up-to-date version
export DOCKER_IMAGE=rocker/rstudio:4.3.2

mkdir $HOME/workdir
chmod 777 $HOME/workdir


docker run -d --name ${NOTEBOOK_CONTAINER_NAME} \
--restart unless-stopped \
--network ${NETWORK_NAME} \
-e DISABLE_AUTH=true \
-v /home/ssm-user/workdir:/home/rstudio \
${DOCKER_IMAGE}

Versioning

Semantic versioning is used and containers are tagged based on GitHub tags: If a tag, v1.2.3 is pushed to GitHub then a container image is built with tags 1.2.3 as well as 1.2. Thus the major.minor tag is overwritten when the repo' is patched.

Security

Trivy is run on each built container and they will not be published to ghcr.io if any CRITICAL or HIGH vulnerabilites are found. Trivy is also run daily to check for new vulnerabilities in existing images. So periodic review of new findings is needed: Go to the Security tab in GitHub, select Code Scanning at left, and then select Branch > Main to check for new findings. To suppress false positives, either:

  • Enter the CVE in .trivyignore, or

  • Enter the file to skip while scanning in the trivy.yml workflow.

In either case, add a comment justifying why the finding is suppressed.
