etcdctl recursive delete with wildcards

[timothysc]

There are times where is would be very useful to recursively delete based on wildcard.

e.g. rm -rf /foo/bar/*

We have remove recursively functonality:

unihorn@CoreOS ~/g/s/g/c/etcd> ./bin/etcdctl --no-sync rm --help
   rm - remove a key

USAGE:
   command rm [command options] [arguments...]

OPTIONS:
   --dir        removes the key if it is an empty directory or a key-value pair
   --recursive      removes the key and all child keys(if it is a directory)
   --with-value     previous value
   --with-index '0' previous index

[timothysc]

what about the wild-cards?

--recursive removes the key and all child keys(if it is a directory)

@timothysc What you want here is the ability to do this:

Give the following keys:

/foo/bar/a
/foo/bar/b
/foo/bar/dir/a
/foo/bar/dir/b

After running the following command:

rm -rf /foo/bar/*

You want the following keys to exist:

/foo/bar/dir/a
/foo/bar/dir/b

Does that look right?

[timothysc]

@kelseyhightower yup.

I ended up here looking exactly for what's requested. I ended up doing a etcdctl ls -recursive, greping for the keys I wanted to remove and feeding them to etcdctl rm

[timothysc]

@olibob great minds think alike ;-)

Anyway... I know upstream is not to keen on treating it as a file-system, but users would ideally like to perform all the traditional ops. IMHO a fuse mount would enable, and folks could just say they _will not_ support the entirety of POSIX semantics.

Then I could just perform traditional shell commands and be done with it vs. trying to force fit through etcdctl

[jeremyeder]

Sounds like I'm not the only one that wants etcdctl to become a full-fledged etcd CLI client...

:+1:

Just chanced across this, but wouldn't the shell fill in the * before passing it into etcdctl?

I am inclined to close this. We do not actively working on v2 anymore. v3 does not support the concept of dir, so this is not an issue anymore.

[timothysc]

sgtm

[rustyx]

For etcd v3 use etcdctl del --prefix=true <prefix>

That will delete everything starting with <prefix>
