Basic Commands

1) Build with Docker

  • Before building a docker image, ensure you have created a Docker file with the format:
  # syntax=docker/dockerfile:1

  FROM node:18-alpine
  WORKDIR /app
  COPY . .
  RUN yarn install --production
  CMD ["node", "src/index.js"]
  EXPOSE 3000

N/B: Change the commands as per the programming language used for the project.

  • Build a docker image:
  docker build -t projectname .

N/B: For the image name, it is best to use the project name to avoid confusion. In addition to that, it creates an image with the tag (name) projectname.

  • Run the container hosting the server component:
  docker run --name=projectname --rm --detach projectname

N/B: For the container name, it is best to use the project name to avoid confusion. In addition to that, it also starts a container named projectname.

  • Inside the projectname container created previously, invoke the client binary:
  docker exec -it projectname /bin/client

N/B: For the container name, it is best to use the project name to avoid confusion. Moreover, it also starts a container named projectname.

  • Stop the container after testing:
  docker stop projectname

2) Push the Docker image to Docker Hub

  • First sign in to Docker Hub:
  docker login -u username
  • Replace the image name:
  docker tag image_name username/image_name
  • Push the image to Docker Hub:
  docker push username/image_name
  • Start the app container using the specified image:
  docker run -dp 127.0.0.1:3000:3000 imagename
  • List the containers:
  docker ps
  • List the docker images:
  docker image ls
  • Delete the Docker container:
  docker rm container_id
