How do I automatically deploy from Travis CI with the container-based infrastructure?

问题

When I use the Travis CI "container-based" infrastructure, I must have

sudo: false

set in my .travis.yml; but this appears to be incompatible with automatic deployment using, for example

deploy:
  provider: hackage

which causes my build to fail with

Installing deploy dependencies
sudo: must be setuid root

How can I use automatic deployment from Travis CI with the container-based infrastructure?

---

The final lines of the build log, starting with successful completion of the code build and test are:

The command "stack $ARGS --no-terminal --install-ghc test --haddock" exited with 0.

回答1:

This isn't possible with the Travis CI "container-based" infrastructure, because Hackage depends on cabal, which requires sudo.
