Because the apt-get update is not run, your build can potentially get an outdated version of the curl and nginx packages. Using RUN apt-get update && apt-get install -y ensures your Dockerfile installs the latest package versions with no further coding or manual intervention. This technique is known as cache busting. You can also achieve cache-busting by specifying a package version. This is known as version pinning, for example:

Best Practices for Using Docker Hub for Ci/Cd
Continuous Integration (CI) is the part of the development process where you’re looking to get your code changes merged with the main branch of the project. At this point, development teams run tests and builds to vet that the code changes don’t cause any unwanted or unexpected behaviors. There are several uses for Docker at this stage of development, even if you don’t end up packaging …

Use Docker Desktop for Mac or Docker Desktop for Windows. Use Docker Engine, if possible with userns mapping for greater isolation of Docker processes from host processes. Don’t worry about time drift. Always run an NTP client on the Docker host and within each container process and sync them all to the same NTP server. If you use swarm services, also ensure that each Docker node syncs its clocks to the same time source as the containers.

10 Docker Apt Best Practices – CLIMB
By following these best practices, you can ensure that your applications are secure, performant, and scalable. 1. Use apt-get update. When you use apt-get update, it updates the list of available packages and their versions. This ensures that when you install a package, you get the latest version available. Without running apt-get update, you may end up with an outdated version of the package which could lead to security vulnerabilities or other issues.

T he next set of best practices will look at how we can optimize for maintainability, security, and repeatability of the Dockerfile. Maintainability Tip #6: Use official images when possible. Official images can save a lot of time spent on maintenance because all the installation steps are done and best practices are applied. If you have multiple projects, they can share those layers because they use exactly the same base image.

`RUN apt-get` is the primary method of package installation in most (Linux-based) Dockerfiles. As with any other package management system, it’s critical to specify the version of each package you install to promote stability. And no, using latest doesn’t count — it’s subject to the same issues as failing to specify a version at all.

How to use apt install correctly in your Dockerfile. Set DEBIAN_FRONTEND=noninteractive to prevent some packages from prompting interactive input ( tzdata for example), which leads to indefinite waiting for an user input. Run apt update before the install command to fetch the current package lists.

The Docker best practices documentation also used to say that if a package contained in the parent image is out-of-date, contact its maintainers. It would indeed be nice if base images always had security updates. But let’s see what real world base images are like. Here’s our Docker file, using the official ubuntu image as its base image.

Sometimes apt-get update is getting slow, it has nothing to do with docker itself. If you have bad connection packages might fail to download completely. As you said, each line in Dockerfile will create an image layer, and cache will be saved locally, to speed up image creation.

Remove APT cache (for Dockerfile) · GitHub – Gist
In a proper container deployment environment you would never need to run apt again after the Docker image was built, you would redo the docker image and repush that image itself. In fact, it is often needed to be able to install new binaries on an instance when something is going wrong and you need to debug things.
