Usage

Overview

doozer is a client for the Doozer Lock Service as implemented by the doozerd(8) binary. It can be used to perform any kind of doozer lock service operation which is supported by the API, such as creating or updating entries, watching them for changes or listing contents of arbitrary trees on the lock service.

Options

Each command takes zero or more options and zero or more arguments. In addition, there are some global options that can be used with any command.

Global options are:

-a=URI

Connect to the given doozer service. The URI can contain an arbitrary number of address parts concatenated by an ampersand character (&). An URI always starts with the prefix doozer:?. Valid options include:

ca

specifies the "cluster address", which could be an IP address and port combination or a host name with a port appended to it.

cn

specifies a cluster name which will be looked up from the lock servers specified in the environment variable DOOZER_BOOT_URI(whichalsocontainsadoozerURI).

sk

can specify a shared key which is used to authenticate to the lock service.

An example URI would look like this:

doozer:?ca=doozer1.example.com&ca=doozer2.example.com&sk=letmein

-b=URI

specifies the Doozer Boot URI which is used to resolve any cluster names passed in the -a flag. It shares the same syntax as -a.

-h

shows a short context help.

-r=rev

specifies the revision number for commands which optionally accept one.

-v

tells doozer to print its version string.

Commands are:

add path

Add a key only if it isn't already set. Takes the file input from stdin.

del path rev

Deletes the file if it is older than revision rev.

find path

Lists all files under the given path.

get path

Fetches the contents of the entry at path and displays it to stdout.

help command

Displays detailed help for the given command.

nop

Just wait for consensus between all lock servers and return.

rev path

Display the current revision of path.

set path rev

Sets the contents of path to the contents read from stdin if it's older than rev.

stat path

Prints the current status of the entry at path.

touch path

Update the revision of the file at path.

wait glob

Wait until a change occurs in an entry which matches glob.

watch glob

Watch for changes in entries which match glob. Prints all changes to such entries to stdout.

Environment

The following environment variables are honored:

DOOZER_URI

The doozer cluster to bind to; overridden by -a.

DOOZER_BOOT_URI

The DzNS to lookup address in; overridden by -b.

Exit status

The exit status is 0 on success, 1 for a rev mismatch, and 2 otherwise.
