can you make sure you use the latest version of default.env ? There were a lot of Docker changes that require new variables. I just did a fresh build tonight and it worked for me. You should see stuff like

LH_SRC_BUILD_TARGET=$(git describe --tags $(git rev-list --tags --max-count=1))
LH_DOCKER_TAG=v0.3.4 # eventually stable or stable-latest when sigp introduce that
# Change to Dockerfile.source to build from source
LH_DOCKERFILE=Dockerfile.binary
LH_USER=lighthouse

also the pipeline test was able to successfully launch the default container too.

In addition, I broke the Lighthouse build for a few hours. You might have grabbed it "in between". As danbryan said, please git pull again, and make sure to use a new copy of default.env to bring your specific changes into.

Side note: I've had OpenEthereum corrupt my mainnet database, once again. The fix they have in dev didn't do the trick. Your mileage will vary.

There was another mistake in default.env. This should be fixed now. Closing for now, please holler if you still have issues, and thank you for your patience.
