[phlax]

oops approved and didnt add change request...

[phlax]

@daixiang0 looks good

while testing out the docs i realised that there are some other problems that need to be fixed first - the existing instructions dont work correcctly - and this makes it worse

ill create a PR to fix docs shortly...

@daixiang0 i created 2 prs to address issues uncovered while testing your PR

one was an ongoing issue in relation to the docker docs #16380 and the other related to the distroless image in particular #16383

im happy for this to land in the meantime

[daixiang0]

Thanks a lot!
