I am using a Kubernetes deployment with etcd+s3, and I am facing issues with data loss when redeploying services. How can I persist metadata in the etcd service to prevent data loss?

To persist metadata in the etcd service in a Kubernetes deployment, you need to configure the --data-dir
and --wal-dir
options for etcd.
The default data directory for etcd is /var/lib/etcd
, and it can be configured using the --data-dir
flag.
Additionally, you can set the --wal-dir
flag to specify the write-ahead log directory for etcd.
By setting these directories to persistent volumes, you can ensure that the metadata and data in etcd are not lost during service redeployment.
It's important to configure these directories properly to prevent data loss and maintain the integrity of the etcd service.
Example:
./etcd --data-dir=/path/to/data/dir --wal-dir=/path/to/wal/dir
