Docker Node.js EPIPE error


Recently, my Node.js app running inside a Docker container started crashing with the error:

Fatal error occurred. Exiting the app. (err.code=EPIPE)
    Error: write EPIPE
        at process.target._send (internal/child_process.js:806:20)
        at process.target.send (internal/child_process.js:676:19)
        at sendHelper (internal/cluster/utils.js:22:15)
        at send (internal/cluster/child.js:190:10)
        at EventEmitter.cluster._getServer (internal/cluster/child.js:89:3)
        at listenInCluster (net.js:1362:11)
        at Server.listen (net.js:1437:7)

I discovered this was caused by not allocating enough Memory and Swap in Docker Desktop > Settings > Resources > Advanced.

Once I doubled it for both, the error disappeared:

Docker Resources
