Docker

Docker is an open platform for developing, shipping and running applications. It enables you to separate your applications from your infrastructure so you can deliver software quickly.

By using Docker, image of Cybersource-Commercetools Extension can be created and run in various platforms wherever Docker is supported.

Before using it, make sure to install Docker Desktop in the respective system.

Building the Docker image

Navigate to the root directory of extension and run the following command to build the Docker image

Use appropriate appline of Nodejs and modify the Dockerfile if necessary.

Note: Make sure to remove node_modules folder if it exists before building the image and ensure that Docker is running.

 docker build -t <imagename> .
 Example: docker build -t sample .

where imagename is the name of your choice

Running the Docker image

Once the Docker image is created successfully, you can run the image by setting env variables and port numbers. Use the following command to run the docker image

 docker run -e <env variables> -p <hostport>:<containerport> -d <imagename>
 
 Example: docker run -e CT_PROJECT_KEY=xxx -e CT_CLIENT_ID=xxx -p 3505:3505 -d sample
  • env variables are the key value pairs present in env file, Refer API-Extension-Setup to set env variables and make sure that to maintain -e separately for every env variable setting.
  • hostport is the port number to use in host machine and containerport is the port to be used by the docker container.
  • imagename is the name of the image that you built in the previous step

Note: If you build the image along with env variables settings, then no need to specify the env variables while running docker image

Running the Docker image in AWS
