Couchbase Server

[2.0.2 RN + Manual?]Host name and IP address management in Couchbase

Details

  • Flagged:
    Release Note

Description

- Need ability to use host names that don't revert to IPs
- Need ability to non-disruptively change the IP address of nodes
- When setting up hostname based cluster(using etc/hosts), nodes revert back to ip when a new node is added by Hostname.

From logs:

Decided to change address to "<IP>"

Steps followed:
1.) Install 2.0 GA
2.) Stop couchbase-server
3.) Add ns_name to couchbase-server
4.) remove files per:http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-bestpractice-cloud-ip.html
5.) add hostname to /opt/couchbase/var/lib/couchbase/ip
6.) Start server and configure with beer-sample
7.) Hostname shows up correctly
8.) Add new node by hostname(no need to rebalance)

I really hope we can have this fixed sooner. It's blocking so many local dev environments. The best practice guide never worked for me.

Can we make sure there is a plan for the proper tooling and documentation around this as well? The couchbase-cli will have to be updated to support this option and documentation for the couchbase-cli, the UI and the REST API should be added to the manual for 2.0.2

Reopening as we need to either use this bug or create new ones for:
-Documentation updates: UI, CLI, REST API and also the deprecation of our "in the cloud" documentation along with a specific section on what this new capability is for.
-Tooling as the CLI will need to provide away of performing this as well

2.0.0 way is _forbidden_ since 2.0.1. I don't know if that's documented or not but it must be.

2.0.1 instructions are actually compatible with new code. But manual change of address is not recommended anymore.

Hi Aliaksey,

For testing changes from MB-7398 (Hostname Management), is http://review.couchbase.org/#/c/25463/3/CHANGES the right place to look for usage?

Does this also mean, the older way http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-bestpractice-cloud-ip.html is/not valid anymore?

Could you confirm?

thanks,
Ketaki

Hi Maria,

For the changes done related to MB-7398 (Hostname Management), I think I need more information on what changes have been done. Is there any specs or documentation that you are aware of related to this?
And also need to find out if our earlier mechanism of hostname configuration is still valid:

Deep --

Scenarios to confirm:
AWS: After upgrade, verify that the host is reachable by hostname (DNS resolution) even if private IP in amazon changed
AWS: After restart of instance, verify same as above.

Thanks,
Maria
