Issues and Questions with Docker Set Up

[lchang256]

Hi, I am trying to get the RISCDuino running with containers, and I have run into some issues and have questions:

1. The docker install instructions is no longer valid for Ubuntu 22.04. I found 22.04 instructions and installed docker.
2. After installing docker, do I pull the repo into riscduino/openlane docker or outside of it? I tried both, but if I tried inside of the docker, it couldn't find the verilog/gz folder. If I tried it externally, I couldn't get the OPENLANE environment.
3. The instructions and steps for RTL sim and GDS run are not clear. First, the riscduino/dv_setup:mpw9 docker image isn't available. The closest I found is mpw6. However, in that docker image, the simenv command isn't available and I can't get make file to make the DV tests, for example make verify-wb_port can't make the test. The MPW6 image has /opt/caravel and /opt/pdk directories but MPW9 image doesn't have the /opt/caravel directory. So I couldn't make or perform sims in MPW9.
