Using latest is prone to errors if the image will ever update. Pin the version explicitly to a release tag

Pin versions in apt get install. Instead of `apt-get install <package>` use `apt-get install <package>=<version>`

Set the SHELL option -o pipefail before RUN with a pipe in it. If you are using /bin/sh in an alpine image or if your shell is symlinked to busybox then consider explicitly setting your SHELL to /bin/ash, or disable this check

Delete the apt-get lists after installing something
