Docker containers
This adds an automatically build Docker container using GitHub actions and the GitHub container registry.
This will make it easier to use elements in node packages like Citadel or Umbrel.
Inspired by the lncm docker bitcoin container: https://github.com/lncm/docker-bitcoind
The docker container now has been tested on Citadel and seems to work successfully, I am syncing the chain with it currently.
I'll now also add a workflow to make sure the container is also built when a new tag is created.
Hi Aaron, I appreciate you put effort into this. Similarly to Bitcoin Core, Elements is very cautious when it comes to official distributed binaries. Both projects distribute only reproducible binaries to reduce the risk of supply chain attack. Both projects would not distribute official docker containers that increase the attack surface.
For these reasons I don't expect this PR to ever be accepted into this repo. Instead we strongly recommend that distributors be responsible for their own builds. It would be best to maintain your docker build definitions elsewhere.
Aaron informed me that he has reproducible docker containers working for other components. That would be interesting to consider here.
Not necessarily as the "supported" distribution but it's at least less dangerous than how other people distribute binary docker containers without any verifiability.
If I understand it correctly, Debian these days is reproducible but not clean bootstrap verified?
Hello @AaronDewes Blockstream publishes docker images that package the official gitian-built Elements binaries. https://hub.docker.com/r/blockstream/elementsd
The image is very simple, you will need to specify an entrypoint and volumes for conf and data.
For example, running the elementsd in regtest mode in a terminal:
docker run -it --entrypoint /usr/local/bin/elementsd blockstream/elementsd:0.21.0.2 -regtest -daemon=0
