Thank you for your time.

Team RabbitMQ uses GitHub issues for specific actionable items engineers can work on. GitHub issues are not used for questions, investigations, root cause analysis, discussions of potential issues, etc (as defined by this team).

We get at least a dozen of questions through various venues every single day, often light on details.
At that rate GitHub issues can very quickly turn into a something impossible to navigate and make sense of even for our team. Because GitHub is a tool our team uses heavily nearly every day, the signal/noise ratio of issues is something we care about a lot.

Please post this to rabbitmq-users.

Thank you.

See How to Troubleshoot Peer Discovery (hint: most decisions are logged at debug level), How Does Peer Discovery Work (and when it is not performed), and finally, some Kubernetes-specific prerequisites.

While not really applicable to Kubernets as the log message says, the range of values in cluster_formation.randomized_startup_delay_range used in your config is very narrow and too unlikely to address the problem it was designed to address. The default range is [5, 60]. With [0, 2] for the range both nodes will effectively boot in parallel.

On an unrelated note, two node clusters are highly discouraged because computing a majority of nodes in case of connectivity loss is impossible. Some features in 3.8 will require a 3+ node cluster.

Remote access for user guest is highly discouraged.

One of the log files contains the following clue:

2019-09-29 09:47:22.846 [info] <0.234.0> k8s endpoint listing returned nodes not yet ready: rabbitmq-0
2019-09-29 09:47:22.846 [info] <0.234.0> All discovered existing cluster peers:

According to the Kubernetes API, the pod of the discover peer is not yet initialised. This is the case when the pods are booting in parallel. See this rabbitmq-users thread, for example. The docs now explicitly warn about this:

Stateless sets are also prone to the natural race condition during initial cluster formation, unlike stateful sets that initialise pods one by one.

Peer discovery mechanism will filter out nodes whose pods are not yet ready (initialised) according to the Kubernetes API. For example, if pod management policy of a stateful set is set to > Parallel, some nodes can be discovered but will not be joined.

It is therefore necessary to use OrderedReady pod management policy for the sets used by RabbitMQ nodes. This policy is used by default by Kubernetes.

Clearer log message when peer discovery yields an empty list
7e2021c 
With some backends, namely Kubernetes, a set of nodes can be
discovered but then filtered out as ineligible. For example,
a node whose pod is not yet ready would not be considered for
clustering.

Hopefully it would reduce the frequency of questions such as [1][2].

@michaelklishin Thank you for your reply.I have a another try without the "cluster_formation.k8s.address_type = hostname" , and other configurations do not change like "cluster_formation.randomized_startup_delay_range".

I'm not sure what the question is.

At the end of the log a peer joins the cluster:

2019-09-29 02:30:14.075 [info] <0.452.0> node 'rabbit@172.31.92.123' up
2019-09-29 02:30:14.424 [info] <0.452.0> rabbit on node 'rabbit@172.31.92.123' up

If you want to see what Kubernetes API endpoint responses return, set log level to debug.
Previously initialised (as in data directory) nodes must be reset between clustering attemptes or they will behave as "rejoining nodes" which the docs cover.

For our team GitHub is not a support forum => I am locking this issue. Please iuse the mailing list in the future.
