What I did
Removed the rules DL3017, DL3031, DL3039.
Adjusted rule DL3035 to allow upgrades, but not dist-upgrades.
How I did it
Adjusted the rule DL3035 and its test.
Deleted the other rules and their tests.
Removed rules from
Spec.hs
andProcess.hs
.Updated README,
hadolint.cabal
using hpack, andcontrib/hadolint.json
.Why i did it
The rationale of not allowing container upgrades inside containers is outdated (#562) and changes are already made to adjust other rules (#592) following the same advice.
