consuldotnet/Consul/KV.cs

Lines 354 to 362 in 269b5bd

 /// <summary> 

 /// DeleteTree is used to delete all keys under a prefix 

 /// </summary> 

 /// <param name="prefix">The key prefix to delete from</param> 

 /// <returns>A write result indicating if the recursive delete attempt succeeded</returns> 

 public Task<WriteResult<bool>> DeleteTree(string prefix, CancellationToken ct = default(CancellationToken)) 

 { 

 return DeleteTree(prefix, WriteOptions.Default, ct); 

 }

Is that what you're looking for?

Thanks for the reply!

That call goes to here:

consuldotnet/Consul/KV.cs

Lines 370 to 376 in 269b5bd

 public Task<WriteResult<bool>> DeleteTree(string prefix, WriteOptions q, CancellationToken ct = default(CancellationToken)) 

 { 

 KVPair.ValidatePath(prefix); 

 var req = _client.DeleteReturning<bool>(string.Format("/v1/kv/{0}", prefix.TrimStart('/')), q); 

 req.Params.Add("recurse", string.Empty); 

 return req.Execute(ct); 

 }

which calls:

consuldotnet/Consul/KV.cs

Line 372 in 269b5bd

KVPair.ValidatePath(prefix);

which in turn calls:

consuldotnet/Consul/KV.cs

Lines 56 to 67 in 269b5bd

 static internal void ValidatePath(string path) 

 { 

 if (string.IsNullOrEmpty(path)) 

 { 

 throw new InvalidKeyPairException("Invalid key. Key path is empty."); 

 } 

 else if (path[0] == '/') 

 { 

 throw new InvalidKeyPairException(string.Format("Invalid key. Key must not begin with a '/': {0}", path)); 

 } 

 } 

 }

When calling List() I am able to pass in "" for prefix to get all the entries and assumed (which could be the problem!) that passing "" into DeleteTree would "delete all", instead it throws an exception as shown above.

Is there another option (other than calling List and deleting one by one?) or is this a bug or perhaps an intentional restriction or something else?

I don't see a way to drop all the keys without specifying a prefix from the docs https://www.consul.io/commands/kv/delete

How would you achieve this with Consul CLI?

I don't see a way either. Ok. I'll use the workaround for now of getting all the keys and deleting them one by one.

Thanks!
