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.
