Make MAX_PEERS editable #72

Closed jterrier84 closed 3 years ago

jterrier84 commented 3 years ago

Actual situation The environment variable MAX_PEERS can not be edited. It seems that it gets overwritten to a fixed value =15 in the topologyUpdate script.

New situation Make the MAX_PEERS variable configurable from outside the container.

jterrier84 commented 3 years ago

After restarting the docker container, the MAX_PEERS variable was loaded into the topologyUpdater file.

tdiesler commented 3 years ago

I verified that -e MAX_PEERS=6 works as expected and results in a topology update request with the corresponding parameter. However, I also observe this https://github.com/cardano-community/guild-operators/issues/1082

Note, the topology file is NOT dynamically reloaded. Instead it requires a restart of the node or in our case a restart of the container. For the topology to survive a restart, it must be written to a persistent volume.

Leaving open for now.

This should be fixed now (on their end)
