@ThEditor I really appreciate your initiative of looking into this and creating a pull request. We already have some work planned on #11443 to overhaul our docker setup for development purposes. As I can see from this PR, you look pretty familiar with Makefile, dockerfile and I can observe your enthusiasm to solve this.

We will love your help with #11443, so can you please email me on -- [email protected] (we will schedule a google meet), we will together work to complete #11443.

Closing this PR in favour of #11443.
