For adjusting `/dev/shm` this is how we patch it in the old sessions:
{
"type": "application/json-patch+json",
"patch": [
{
"op": "add",
"path": "/statefulset/spec/template/spec/volumes/-",
"value": {
"name": "shm",
"emptyDir": {
"medium": "Memory",
# NOTE: We are giving /dev/shm up to half of the memory request
"sizeLimit": int(server.server_options.storage / 2),
},
},
},
{
"op": "add",
"path": "/statefulset/spec/template/spec/containers/1/volumeMounts/-",
"value": {
"mountPath": "/dev/shm",
"name": "shm",
},
},
],
}
So it is a memory backed volume mounted at /dev/shm. And its size is half the memory request for the session. Here we can make it part of the CRD with a default value of 1Gi or something like that.
