Con-PCA API

Required for install:

This is a Docker skeleton project that can be used to quickly get a new cisagov GitHub Docker project started. This skeleton project contains licensing information, as well as pre-commit hooks and GitHub Actions configurations appropriate for Docker containers and the major languages that we use.

Running

Running with Docker

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

docker run cisagov/con-pca-api:0.0.1

Running with Docker Compose

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

   ---
   version: "3.8"
   
   services:
     api:
       image: cisagov/con-pca-api: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

2. Start the container and detach:

   docker compose up --detach

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. See the secrets section below for a table of all supported secret files.

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

   Better lock it in your pocket.
   

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

   ---
   version: "3.7"
   
   secrets:
     quote_txt:
       file: quote.txt
   
   services:
     api:
       image: cisagov/con-pca-api: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
       secrets:
         - source: quote_txt
           target: quote.txt

Updating your container

Docker Compose

1. Pull the new image from Docker Hub:

   docker compose pull

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

   docker compose up --detach

Docker

1. Stop the running container:

   docker stop <container_id>

2. Pull the new image:

   docker pull cisagov/con-pca-api:0.0.1

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-api project that they containerize. It is recommended that most users use a version tag (e.g. :0.0.1).

Image:tag	Description
cisagov/con-pca-api:1.2.3	An exact release version.
cisagov/con-pca-api:1.2	The most recent release matching the major and minor version numbers.
cisagov/con-pca-api:1	The most recent release matching the major version number.
cisagov/con-pca-api:edge	The most recent image built from a merge into the develop branch of this repository.
cisagov/con-pca-api:nightly	A nightly build of the develop branch of this repository.
cisagov/con-pca-api:latest	The most recent release image pushed to a container registry. Pulling an image using the :latest tag should be avoided.

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

git clone [email protected]:cisagov/con-pca-api.git

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-api:0.0.1 \
  https://github.com/cisagov/con-pca-api.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-api.git
   cd con-pca-api

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

   ./buildx-dockerfile.sh

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-api:0.0.1 .
