DS diagnostic tools

Debug script

The bin/ds-debug.sh script lets you obtain diagnostic information for any DS pod running in your cluster. It also lets you perform several cleanup and recovery operations on DS pods.

Run bin/ds-debug.sh -h to refer to the command’s syntax.

The following bin/ds-debug.sh subcommands provide diagnostic information:

Subcommand Diagnostics

status

Server details, connection handlers, backends, and disk space

rstatus

Replication status

idsearch

All the DNs in the ou=identities branch

monitor

All the directory entries in the cn=monitor branch

list-backups

A list of the backups associated with a DS instance

The following bin/ds-debug.sh subcommands are operational:

Subcommand Action

purge

Purges all the backups associated with a DS instance

disaster

Performs a disaster recovery operation by executing the dsrepl start-disaster-recovery -X command, and then the the dsrepl end-disaster-recovery -X command

Debug tools container

The ds-util debug tools container provides a suite of diagnostic tools that you can execute inside of a running Kubernetes cluster.

The container has two types of tools:

  • DS tools—A DS instance is installed in the /opt/opendj directory of the ds-util container. DS tools, such as the ldapsearch and ldapmodify commands, are available in the /opt/opendj/bin directory.

  • Miscellaneous diagnostic tools—A set of diagnostic tools, including dig, netcat, nslookup, curl, and vi, have been installed in the container. The file, /path/to/forgeops/docker/ds/dsutil/Dockerfile, has the list of operating system packages that have been installed in the debug tools container.

To start the debug tools container:

$ kubectl run -it ds-util --image=gcr.io/forgeops-public/ds-util -- bash

After you start the tools container, a command prompt appears:

root@ds-util:/opt/opendj#

You can access all the tools available in the container from this prompt. For example:

root@ds-util:/opt/opendj# nslookup am
Server:		10.96.0.10
Address:	10.96.0.10#53

Name:	am.my-namespace.svc.cluster.local
Address: 10.100.20.240
