Rundeck VS Apache ZooKeeper

I don't use it myself, but I think rundeck might be what you're looking for

Have a look at rundeck.org

Not possible at this moment, please suggest that here.

Hi, that's an odd issue (never happened on my env, but reported here), you can try this or this.

If you want a web panel, I believe you could achieve that with Rundeck.

I found this info here and here.

Changing default SCM SSH authentication to SSHJ: The SCM integration now uses SSHJ for SSH authentication by default (previously JSCH). GitHub has tightened up their SSH key requirements and now requires SSH-RSA 2 keys. The new default for ssh-keygen via OpenSSH is not supported by JSCH.

Firstly, I tried Rundeck and Apache Airflow. They are complete overkill for what I want to do. Then I found Cronicle which is light enough, besides it can pull double duty as a general purpose scheduler.

Yesterday we posted a Security Advisory to Github for a critical vulnerability in Rundeck Community and Rundeck Enterprise Docker images, versions 4.0 and earlier. Those Docker images contained a pre-generated SSH key pair in the default file path. If that key was used to configure SSH access to hosts, they would allow access to anyone with the exposed private key.

Zookeeper is a distributed coordination service used in older versions of Kafka to manage cluster metadata, leader election, and configuration. It ensures consistency and synchronization across Kafka brokers.

Using a service discovery mechanism: A service discovery mechanism, such as etcd or ZooKeeper, can help to manage the complexity of microservices by providing a centralized registry of available services and their instances.

Apache ZooKeeper: A centralized service to generate unique IDs and prevent race conditions between instances.

Apache ZooKeeper — a distributed coordination, synchronization, and configuration service (written in Java);

To use Kafka, we also need to deploy a service that keeps configuration informations such as Zookeeper.

Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service.

zookeeper: is (was?) used for secrets management. it was also used as a basic health check, but has been since been replaced.

You can install Kafka from https://kafka.apache.org/quickstart. Because Druid and Kafka both use Apache Zookeeper, I opted to use the Zookeeper deployment that comes with Druid, so didn’t start it with Kafka. Once running, I created two topics for me to post the data into, and for Druid to ingest from:

Please note that we use Zookeeper as the Governance Center.
