Installation
composer require linkorb/etcd-php
Usage
The client
Instantiate the client
$client = new Client($server);
Instantiate the client with custom Guzzle Client
$client = Client::constructWithGuzzleClient($guzzleClient, $server);
Use the client instance
$client->set('/foo', 'fooValue'); // Set the ttl $client->set('/foo', 'fooValue', 10); // get key value echo $client->get('/foo'); // Update value with key $client->update('/foo', 'newFooValue'); // Delete key $client->rm('/foo'); // Create a directory $client->mkdir('/fooDir'); // Remove dir $client->rmdir('/fooDir');
The command line tool
Setting Key Values
Set a value on the /foo/bar
key:
$ bin/etcd-php etcd:set /foo/bar "Hello world"
Set a value on the /foo/bar
key with a value that expires in 60 seconds:
$ bin/etcd-php etcd:set /foo/bar "Hello world" --ttl=60
Create a new key /foo/bar
, only if the key did not previously exist:
$ bin/etcd-php etcd:mk /foo/new_bar "Hello world"
Create a new dir /fooDir
, only if the key did not previously exist:
$ bin/etcd-php etcd:mkdir /fooDir
Update an existing key /foo/bar
, only if the key already existed:
$ bin/etcd-php etcd:update /foo/bar "Hola mundo"
Create or update a directory called /mydir
:
$ bin/etcd-php etcd:setDir /mydir
Retrieving a key value
Get the current value for a single key in the local etcd node:
$ bin/etcd-php etcd:get /foo/bar
Listing a directory
Explore the keyspace using the ls
command
$ bin/etcd-php etcd:ls /akey /adir $ bin/etcd-php etcd:ls /adir /adir/key1 /adir/key2
Add -recursive
to recursively list subdirectories encountered.
$ bin/etcd-php etcd:ls --recursive /foo /foo/bar /foo/new_bar /fooDir
Deleting a key
Delete a key:
$ bin/etcd-php etcd:rm /foo/bar
Delete an empty directory or a key-value pair
$ bin/etcd-php etcd:rmdir /path/to/dir
Recursively delete a key and all child keys:
$ bin/etcd-php etcd:rmdir /path/to/dir --recursive
Export node
$ bin/etcd-php etcd:export --server=http://127.0.0.1:2379 --format=json --output=config.json /path/to/dir
Watching for changes
Watch for only the next change on a key:
$ bin/etcd-php etcd:watch /foo/bar
