Docker "latest" tag is not found

[SteMak]

Overview

Docker tag latest is useful as it is possible for scripts using the docker image to be always up-to-date.

Problem

No latest tag found:

docker: Error response from daemon: manifest for \
cosmwasm/rust-optimizer:latest not found: manifest unknown: manifest unknown.

Note

If it may happen that latest tag may be unstable, provide additional stable tag for marking container version tested by time.

What's the use case for that? The builder version should be fixed. Otherwise your builds are not reproducible.

[SteMak]

The main use case is developing.
Of course, for production all unstable versions should be locked, but for developing it is better to upgrade dependencies automatically to use the latest version with the newest features.

One more point: template projects, documentation, etc. should not be modified any time new version is released.
Example: CosmWasm Docs contains outdated rust-optimizer version and may be easy fixed by using latest tag.

[webmaster128]

I see your point. However, we should discourage any sort of usage of this project without version pinning as this creates builds that are not reproducible. We should clarify this as part of #101.
