Bulk Delete Configurations

Hello,

Any way to bulk delete configurations? I realize I have created 30000
instances of a factory pid which shouldn't be there. I know I can create a
script to delete the pids. Just wondering whether there may be another way.

thanks in advance,
Gareth

Hi Gareth,

In a programmatic way, that's relatively easy. You can use the Configuration Admin Service and call listConfigurations(String filter), with a filter like "(service.factoryPid=YouFactoryPid)". Then you can call delete() on all of the returned Configuration objects. Beware that the ConfigAdmin returns null rather than an empty array in case there is no configuration matching the filter. (See docs [1][2]).

I'm unaware of an easy possibility to do this with a script "from outside", i.e. the console or similar.

Regards,
Benjamin

Thanks for all the answers! I actually tried something like this (the tee was
to put the output to file - is there a better way?):

karaf@root> config:list "(<my pid query>)" | grep service.pid | exec tee
/tmp/badconfigs.txt

Then this to create the commands (there were some weird characters in the
output):

sed --expression="s/.*=/config:delete/g;s/...$//g" badconfigs.txt 

which I could then feed into karaf.

One thing I noted - when I tried to add the "sed" expression to the karaf
command line the execution became very slow (even the tee slowed down karaf
a lot). I guess that is just a limitation of the implementation? Also is
there any way to pipe the commands into karaf directly for execution without
using a temporary file?

thanks in advance,
Gareth

By the way, I think config:delete accept wildcard (my.pid*) AFAIR.
If not, it could be a good addition ;)

Hi Gareth,

You can do that:
- using the ConfigAdmin service programmatically
- using the ConfigMBean (remotely programmatically)
- using a script that use config:* commands (local or remote using ssh)
