cc ros image maintainer @tfoote -- this looks correct to me, but I'd love if you could confirm :bow:
My use-case: I am coming to the README as a beginner in using docker and ros1_bridge, and the entire readme focuses on using foxy. So the examples fail, which gives a poor experience for newcomers. If the syntax is correct from Humble and onwards, then should the README be changed to use docker images for humble instead of foxy?
Line 16, 47 and 240 in the readme.
Yeah, I think it would be best for us to move the docs forward to the latest LTS release so replace foxy with jazzy
