Very often, docker-compose up doesn't rebuild image specified as "build:" in the docker-compose.yml although the respective Dockerfile has changed. Instead, I need to run docker build -t servicename_foldername . manually for the affected service which will actually update the image accordingly...
they want to update the Docker image or publish the new updates. For this purpose, they may be required to update the application source code, and Docker file, rebuild the application, and release the new version of the image. For illustration, go through the below instructions...
How to Reduce Docker Image Size? If we take a container image of a typical application, it contains a base image,Dependencies/Files/Configs,and cruft(unwanted software). So it all boils down to how efficiently we can manage these resources inside the container image. Let’s look at different...

For example, if you specifyFROM alpine:3.19in your Dockerfile,3.19resolves to the latest patch version for3.19. # syntax=docker/dockerfile:1FROMalpine:3.19 At one point in time, the3.19tag might point to version 3.19.1 of the image. If you rebuild the image 3 months later, the same tag...

You don’t need to rebuild your Docker image in development for each tiny code change. If you mount your code into your dev container, you don’t have to build a new image on every code change and iterate faster. It’s a great feeling when you make changes and see the results right...
Docker speeds up image building by locally caching existing layers of a Dockerfile and using the cache to rebuild images faster. However, the cache is used only for the layers preceding the modified layer. To optimize your image, placeDockerfileinstructions that are likely to change as low in...
Rebuilding the sameDockerfileshould result in the same version of the image being packaged, even if the second build happens several versions later, or the build should fail outright, such that an inadvertent rebuild of aDockerfiletagged as0.1.0doesn't end up containing0.2.3. For example, if...
This means that when the base image is updated, we should rebuild all our images, to make sure that it’s consistent across all our containers. This also means that we need to have good governance and good communication between teams. You might be thinking, “that’s not a technical issue...
