It's worth pointing out that if you don't want a Go build toolchain in your container, you have exactly the same problem. And a Go build toolchain (read: dependency/vendoring management toolchain) actually requires _more_ care and feeding than the analogous Python in my experience; the reason it's superficially appealing is that you can "cheat" and copy the binary over from a development environment, but this is not a robust CI solution. Go's build toolchain has many features worth envying but most of its advantages have to do with deployments _outside_ of containers, where you have to ship to customer environments with fraught and unknown system configurations. If you have any level of control over your deployment target, Go and, say, Python with PEX are ~equivalent. -glyph _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
