V2: sqlg image fails to build

[kuzeko]

The compilation of the docker image stops with an error at

+ mktemp -d
+ export GNUPGHOME=/tmp/tmp.6y4T856Gbp
+ gpg --batch --keyserver hkps://keys.openpgp.org --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4
gpg: keybox '/tmp/tmp.6y4T856Gbp/pubring.kbx' created
gpg: keyserver receive failed: General error

Firewall?

We might just get rid of GPG from the images. Download, verify, and vendor everything. This would also fix Apache stuff disappearing.

You mean add to the repo all the downloaded JARs?

[MartinBrugnara]

Thinking more about the images, like Cassandra, ES, and GOSU.

Maven repo seams a more stable.

[MartinBrugnara]

Alternatively we may setup CI to build once a month (even without merged PRs), this would be enough to catch both disappearing versions and key rotations (like in the case of PG).

I am ok in removing GPG signing and adding a warning in the readme. The others I am not sure, but having a backup is always wise

Sounds good!
