How to Create a Docker Container?
The following are the steps that guides in creating a Docker Container:
step 1: Create a Dockerfile
- Create a Dockerfile with specifying the instructions on building the container.
# Use the official Node.js base image
FROM node:14
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3000
CMD ["node", "app.js"]
Step 2: Build a Docker Image
Now, using the docker build command create a docker image from the created Dockerfile with the following command:
docker build -t my-node-app .
Step 3: run the Docker Container
- Use the following docker run command to start a new container from the image, here running container on port 3000.
docker run -d -p 3000:3000 my-node-app
Step 4: Verify the Container Running State
- Check the list of the running containers in the list with the following command:
docker ps
Step 5: Access the Application
- Open the web browser and navigate to http://localhost:3000 to access your application
http://localhost:3000
Step 6: Manage the Container
- Stop the docker running the state using its container name or id, the command looks as follows:
docker stop <container_id>
- To remove the container use the following command:
docker rm <container_id>
