Next, you can look for the version of the image you need to update to.įor example, this is a screenshot from Docker Hub showing the mysql version we need to use for carrying out the Docker update image task: You may also remove its associated image by using the docker rmi command.

Here is how to remove the mysql container: Step 3: Remove the containerĪfter stopping the running container, you can now use the docker rm command to remove it. It’ll return the ID of the deployed container. Then, stop the existing container by running the docker stop command.įor example, here is how to stop the mysql container: To see a list of all containers, running and not running, add the -a (or –all ) flag. Step 2: Stop the containerĪfter knowing the outdated image version the deployed container is using, the next step is to stop the container.įirst, you’ll need to use the docker ps command to see a list of all containers currently running on your system. Here is the output (for brevity, it’s truncated):įrom the above output, you can see that the version of the bash image, which is tagged as latest, is 5.0.18. Here is the command: docker inspect 39a95ac32011 Note that we got its ID after running the docker images command. Let’s run the command against the bash image on our system. So, to know the exact version of such an image, you may run the docker inspect command, which outputs detailed low-level information about the image. So, it may be confusing to use, at times.įor example, these two commands will both create a new image that is tagged as latest : docker build -t user/image_name. It’s not dynamic and may not track the most recent push. It’s the default tag that Docker applies to any image without a specific tag. Remember that the latest tag may not actually mean that the image is the latest version. If an image is tagged with a version name, such as latest, you may need to dig further to know the exact version of the image. It’s the version tag that we want here.įor example, the version of the mysql image is 8.0. If you check the output of either of the commands, you’ll see that they list the available images, alongside their version tags, IDs, and other stuff. To see the images on your system, run the docker images or docker image ls command.

You can use any of the following two simple methods to check if your image is outdated: You can get this information by looking at the set of identifiers and tags that come with every image pulled from a Docker Registry such as the Docker Hub. To find out if your Docker container requires an upgrade, you need to check the version you are using. Let’s talk about the steps of upgrading a Docker image and a container to the version you desire. How to update Docker images and containers
#Docker remove container for new one Patch#
Updated images often come with patch fixes that can enhance the security of your applications.Here are some reasons for keeping them up-to-date: Unless you have a convincing reason to use an older version, it’s recommended to run Docker containers using the most up-to-date image releases. Importance of updating Docker images and containers
#Docker remove container for new one upgrade#
This article demonstrates how to upgrade a deployed Docker container based on an updated image version. Since images within launched containers cannot self-update, it’s essential to use other ways to keep them up-to-date and optimize your applications’ performance.

And when you’ve used an image to deploy a container, it continues running that image version, even if a new release is existing.

When working with Docker, everything revolves around images.
