3.3. Docker Build<\/h4>\n
Open the terminal (Powershell) and navigate the Web API project path.
\n Run the Docker build command to build the image.
\n Syntax: Docker build \u2013rm -t [dockerimagename]:latest .
\n Example: docker build \u2013rm -t dockerwebapiimage:latest .<\/p>\n
-t stands for tag to tag the image.
\n
\n\u2013rm option automatically removes the container when it exits.<\/p>\n
Note:<\/p>\n
The above steps 3 & 5 end with \u2018.\u2019, which is required to set the current directory.<\/p>\n
\n Fig 9: Docker Build<\/p>\n
3.4. Docker Run<\/h4>\n
A Docker container is a running instance of a Docker image. It allows you to package the application code and its dependencies into a single unit.<\/p>\n
Run the below command to create a docker container from a docker image.
\n Syntax: docker run -d -p host:portno:defaultport [imagename]
\n Example: docker run -d -p 127.0.0.1:5000:8080 dockerwebapiimage
\n Returns the container ID as a response.<\/p>\n
-p stands for port number.<\/p>\n
-d indicates the container should run in detached mode.<\/p>\n
Note: The port number \u20185000\u2019 that was exposed in the docker file has been mapped to the default port.<\/p>\n
\n Fig 10: Docker Run — create container<\/p>\n
3.5. Docker Desktop<\/h4>\n
Docker Desktop can be used in Windows and Mac to manage the various Docker components, including containers, images, volumes, etc.<\/p>\n
Go to Docker Desktop.<\/p>\n
\n Fig 11: Docker Desktop<\/p>\n
Containers<\/p>\n
List all the Docker containers. You can see the newly created container in the list and identify the same with the container ID.<\/p>\n
\n Fig 12: Docker Containers<\/p>\n
Container Details<\/p>\n
Shows the details of the selected container. The logs show the default port number, and the same has been mapped to the Docker file exposed port number during the Docker run execution.<\/p>\n
