Ruby 2.7.3 introduced a new bug with Resolv::DNS, which we heavily use within
Mastodon: https://bugs.ruby-lang.org/issues/17781

Ruby 2.7.3 also included security fixes for two CVEs, but those do not seem
to apply to Mastodon:

Kaniko does not support looking up binaries from $PATH, so we
specify the full path to the bash binary.

thwait and e2mmap are no longer needed in Gemfile.
Gems properly require those.

* Dockerfile: Fix building with multiarch

Tested on amd64 and arm64

* Reduce docker image size by clean up some unneeded source file

* Update Dockerfile

* Update Dockerfile

* Use ARCH variable instead of hardcoded x64

* fix formating

[Rkt](https://coreos.com/rkt) doesn't allow ports to be exposed to containers unless they are declared in the container manifest. Re-adding EXPOSE back in (removed in 1dbf993bce) allows the container to be used on rkt based systems.

* Update Ruby/Node/jemalloc source for Docker Image

* Update Dockerfile

* Update Dockerfile

- Always run apt update before any other apt command. (This fixes
  incremental builds failing if a remote package is updated.)
- Only copy dependency lists before installing dependencies. (This means
  editing code doesn't force all dependencies to be re-downloaded.)
- Delete cache in the same layer that it is created. (Otherwise,
  deleting cache *increases* the size of the image on non-squashed
  builds.)
- Move the installation of some static dependencies to *before* Mastodon
  code is imported to Docker.

* Revert "update vagrant configs (#8706)"

This reverts commit 8971bb8cf2.

* Revert "Updated ruby/node images (#8700)"

This reverts commit 5aae71cf60.

* Dockerfile: run asset precompilation as a build step

* Replace OTP_SECRET and SECRET_KEY_BASE with placeholders
