Setup

• start the cluster

MON=1 OSD=1 MDS=0 MGR=0 RGW=1 ../src/vstart.sh -n -d

• create an http topic:

aws --endpoint-url http://localhost:8000 sns create-topic --name=fishtopic \
  --attributes='{"push-endpoint": "http://localhost:10900"}'

notification retries

phase 0

• limit number of reties (ephemeral)
• notification TTL (persistent)
• spacing the retries (ephemeral)
• global config via options

phase 1

• per topic config via REST
• notification TTL migration
• documentation

yuvalif

• start a vstart cluster

MON=1 OSD=1 MDS=0 MGR=0 RGW=1 ../src/vstart.sh -n -d

• create a lua file that implemets access log and depends on cjson and socket packages

  if Request.RGWOp == "get_obj" then
    local json = require("cjson")
    local socket = require("socket")
    local unix = require("socket.unix")

yuvalif

• start multisite wirh 2 clusters and tracing enabled:

MON=1 OSD=1 MDS=0 MGR=0 ../src/test/rgw/test-rgw-multisite.sh 2 \
  --jaeger_tracing_enable=true --jaeger_agent_port=6831 --debug-trace=20

• start the "all in one" container of jaeger, this will run: the agent, the collector the backend and the UI:

$ podman run \
  -e COLLECTOR_OTLP_ENABLED=true \
 -p 6831:6831/udp \

setup

• deploy a cephadm cluster with a custom build:

sudo cephadm --image <image> bootstrap --mon-ip <ip> --single-host-defaults

• start OSDs:

sudo cephadm shell ceph orch apply osd --all-available-devices

• enable the rgw service there:
