1. Pull the latest version of the image: The first step is to update the Docker image is to pull the latest version from the Docker Hub. You can do this by executing the following command:
\`\`\` docker pull IMAGE\_NAME \`\`\` Replace ‘IMAGE\_NAME’ with the name of the Docker image you want to update.1. Remove the old container: After you have the latest image, the next step is to remove the old Docker container that is running the outdated image. You can remove the old container by executing the following command:
\`\`\` docker rm CONTAINER\_ID \`\`\` Replace ‘CONTAINER\_ID’ with the ID of the Docker container you want to remove.1. Create a new container with the updated image: Once the old container is removed, you can create a new Docker container using the updated image. You can do this by executing the following command:
\`\`\` docker run -d -p HOST_PORT:CONTAINER_PORT —name CONTAINER_NAME IMAGE_NAME \`\`\` – Replace ‘HOST\_PORT’ with the port number on your host machine. – Replace ‘CONTAINER\_PORT’ with the port number on the Docker container. – Replace ‘CONTAINER\_NAME’ with the name you want to give to your Docker container. – Replace ‘IMAGE\_NAME’ with the name of the Docker image you want to use.By following these steps, you can update a Docker image. Note: this may cause a brief downtime for any services running in your container as you have to remove the old container and create a new one. You may want to plan this update during a maintenance window or when your services are least used.
