Requirements:

• Linux
• A linux filesystem if you wish to containerize to a linux environment. You can get one from Alpine Linux

Usage:

How to open a shell window (Alpine linux fs)

gontainer --chrt "/home/alpine-fs" run sh 

How to open a ash window, which is like bash (Alpine linux fs)

gontainer --chrt "/home/alpine-fs" run ash 

Example on how to run python (must be installed beforehand, see Gockerfile)

gontainer --chrt "/home/alpine-fs" run python3 

VFS mount usage:

There is a file included with this repo called mnt-vfs.sh which is a script that creates a size-limited filesystem and mounts it.

Usage:

chmod +x ./mnt-vfs.sh
./mnt-vfs.sh my-fs-name 100 # Will create a 100MB vfs with the name `my-fs-name`

For this example we will create a 2GB image mounted at /mnt/my-vfs. I assume you have a alpine linux filesystem at /alpine-fs and are running everything as root.

wget http://urlTo.thefile/mnt-vfs.sh
chmod +x ./mnt-vfs.sh
./mnt-vfs.sh my-vfs 2000
cp -r /alpine-fs /mnt/my-vfs

Now you have a virtual filesystem ready with a 2GB limit! You can run gontainer on it!

gontainer --chrt /mnt/my-vfs run sh
