sudo apt-get update # Fetches the list of available updates sudo apt-get upgrade # Strictly upgrades the current packages sudo apt-get dist-upgrade # Installs updates (new ones)
A lot of minimal Debian distros don’t have the `ps` process status app by default. There are times it’s useful when you want to inspect a container from the inside, so add:
`apt-get install -y procps`
to your build or manually install it after. Adds about 1MB to your environment.
