How do I mount the docker container filesystem?
How do I mount docker container images so that I can modify them with external tools?
This means: from the docker hosts, installing the image without running the container on it, just like a normal filesystem. I don't need to start the container for this.
I would like to update the image directly this way and then probably send something like
. With tools
(like ubuntu) it's pretty easy as it's available to be hosted in
I know of workarounds, but:
- I don't feel like using context
) is quite convenient and adaptive: I don't have a dedicated directory to upload, but would rather use a combination of tools to modify only certain files (e.g.
- Even if
contains some kind of algorithm that only adds new files to the image appropriately, I still have to send all files as docker context for the build command !.
- I could update the container image by calling the tools preset on the image. But
apt-get install git
doubles the image size. And git won't be used in production. And removing tools after use isn't always that easy, other than that it doesn't feel right.
- I could use the
docker build option to mount a directory full of tools ... and their dependencies. It's tricky if you need more than just a bash - script.
