PYTHON API RUNNING AS CONTAINER

1. How to build a container image

Open a Terminal window (Mac, Linux) or CMD window (Windows) and place yourself in the directory where the source code of your project is. Then, type the following command:

docker build . -t my_api:v1

where:

• "." represents the current directory where you are
• "-t" means you want to tag your container image with name
• "my_api" is the main name of your container image
• "v1" is the part of the tag name related to the container version

2. How to run a container image

Open a Terminal window (Mac, Linux) or CMD window (Windows) and type:

docker run -p 5000:5000 my_api:v1 -it api_container

where:

• "my_api:v1" is the local image you want to run as a container
• "api_container" is the name you want to assign to this container image when it is run.

3. How to open a console inside a container

Open a Terminal window (Mac, Linux) or CMD window (Windows) and type:

docker exec -it <container_id> ash

NOTE: ash is the built-in shell in Alpine linux.
