cisagov/con-pca-web repository overview

⁠Con-PCA Client

⁠Setup and Build

⁠Running with Docker

To run the cisagov/con-pca-web image via Docker:

docker run cisagov/con-pca-web:0.0.1

⁠Running with Docker Compose

1. Create a docker-compose.yml file similar to the one below to use Docker Compose⁠.

   ---
   version: "3.7"
   
   services:
     pca-web:
       image: cisagov/con-pca-web:0.0.1
       volumes:
         - type: bind
           source: <your_log_dir>
           target: /var/log
       environment:
         - ECHO_MESSAGE="Hello from docker compose"
       ports:
         - target: 8080
           published: 8080
           protocol: tcp
   

   Copy

2. Start the container and detach:

   docker compose up --detach
   

   Copy

⁠Using secrets with your container

This container also supports passing sensitive values via Docker secrets⁠. Passing sensitive values like your credentials can be more secure using secrets than using environment variables.

1. To use secrets, create a quote.txt file containing the values you want set:

   Better lock it in your pocket.
   

   Copy

2. Then add the secret to your docker-compose.yml file:

   ---
   version: "3.7"
   
   secrets:
     quote_txt:
       file: quote.txt
   
   services:
     web:
       image: cisagov/con-pca-web:0.0.1
       volumes:
         - type: bind
           source: <your_log_dir>
           target: /var/log
       environment:
         - ECHO_MESSAGE="Hello from docker compose"
       ports:
         - target: 80
           published: 4200
           protocol: tcp
       secrets:
         - source: quote_txt
           target: quote.txt
   

   Copy

⁠Updating your container

⁠Docker Compose

1. Pull the new image from Docker Hub:

   docker compose pull
   

   Copy

2. Recreate the running container by following the previous instructions⁠:

   docker compose up --detach
   

   Copy

⁠Docker

1. Stop the running container:

   docker stop <container_id>
   

   Copy

2. Pull the new image:

   docker pull cisagov/con-pca-web:0.0.1
   

   Copy

3. Recreate and run the container by following the previous instructions⁠.

⁠Image tags

The images of this container are tagged with semantic versions⁠ of the underlying con-pca-web project that they containerize. It is recommended that most users use a version tag (e.g. :0.0.1).

See the tags tab⁠ on Docker Hub for a list of all the supported tags.

⁠Ports

The following ports are exposed by this container:

The Docker composition⁠ publishes the exposed port at 4200.

⁠Environment variables

⁠Required

There are no required environment variables.

⁠Building from source

Build the image locally using this git repository as the build context⁠:

docker build \
  --build-arg VERSION=0.0.1 \
  --tag cisagov/con-pca-web:0.0.1 \
  https://github.com/cisagov/con-pca-web.git#develop

⁠Cross-platform builds

To create images that are compatible with other platforms, you can use the buildx⁠ feature of Docker:

1. Copy the project to your machine using the Code button above or the command line:

   git clone https://github.com/cisagov/con-pca-web.git
   cd con-pca-web
   

   Copy

2. Create the Dockerfile-x file with buildx platform support:

   ./buildx-dockerfile.sh
   

   Copy

3. Build the image using buildx:

   docker buildx build \
     --file Dockerfile-x \
     --platform linux/amd64 \
     --build-arg VERSION=0.0.1 \
     --output type=docker \
     --tag cisagov/con-pca-web:0.0.1 .
   

   Copy
