I am getting 504 GATEWAY_TIMEOUT when pushing to a hosted Docker repo on Sonatype Nexus 3. I'm trying to push a multi-GB layer:
451c9f0946ad: Image already exists
97444a62d0da: Image already exists
3acdb070c7f5: Image already exists
78362681bd49: Image already exists
5890a244c36a: Pushing [==================================================>] 2.403 GB
Received unexpected HTTP status: 504 GATEWAY_TIMEOUT
It seems to error after about 4 to 4.5 minutes. I don't see a way to adjust the timeout on the Nexus side. Any ideas?
