Docker containers (on Linux) don't have a guest OS. They all share the same kernel and only the userland is different depending on which distro you choose for your base.
You can choose to build on a scratch/blank image just as easily, which means nothing except your app itself is in the image.
- ornornor 6y agoYou still have to update the packages or distro your image is based on. It’s not as maintenance free as heroku or google app engine.
- manigandham 6y agoSure, but you can get the latest image automatically as part of your container build. It's not as hard as it seems. Or you can build an image from scratch without any distro and then there's nothing to maintain.
