Debezium series: monitor Debezium cluster status, automatic operation and maintenance of Debezium cluster

1. Demand background

• The Debezium cluster implements service hosting through systemctl, and on this basis, further monitors the status of the Debezium cluster, and restarts the abnormal node when the Debezium cluster node or indicator is abnormal
• Restart Debezium node service remotely based on ansible, and send related information to Feishu alarm group

2. Relevant Implementation Technologies

Meet Ansible:

• Ansible is an open source automation tool for configuring and managing computer systems. It describes system configuration and deployment tasks by using a natural language-like syntax and simple YAML files. Ansible provides easy-to-use yet powerful command-line tools for automating various IT operations such as configuration management, application deployment, cloud configuration, container orchestration, and more. Ansible's core philosophy is to use repeatable, self-documenting, and extensible playbooks to describe the desired state without writing complex scripts or custom code. By communicating with the target host using the SSH protocol, Ansible is able to execute commands and tasks on the remote system and ensure the system reaches the desired state. It supports multiple operating systems, cloud services, and network devices, and has a rich plugin ecosystemÿ
