Update Your Docker Image

If you have your own docker image/s set up, here is how you can push new builds.

Make the necessary changes in your Dockerfile then change to the command line and navigate into the folder where our Dockerfile resides. First we build our image.

docker build -t imagename .

Next we tag it, so it is easy to reference at a later point.

docker tag imagename rafhun/php:tag

Then push the image to the Docker repository. If you do not yet have a Docker ID go ahead and create one here. Then make sure you are logged into Docker Hub.

docker login

Now we are ready to push the image to Docker Hub.

docker push rafhun/php:tag

Hint: Make sure to also add the latest tag to the version you are pushing and push it to Docker Hub as well.

After pushing a new tag to the repository make sure to build images when you are restarting containers by running the following command to start them up.

docker-composer up -d --build

Hint: If you are using a specific tag (other than latest) adjust it before you rebuild the image.
