Download, Build and Install

Service Broker CLI is written in Go. It is designed to use only standard libraries.

It provides also a Makefile, so it's quite easy to build and install.

Downlad the repo with go get github.com/phartz/service-broker-cli, then change the current path to the sources cd $GOPATH/src/github.com/phartz/service-broker-cli.

Build

make

Install

make install

Either add the $GOPATH/bin export PATH=$PATH:$GOPATH/bin to your $PATH or copy the cli to your bin folder cp sb /usr/local/bin

To get specific help use sb help <command>

Restrictions

There are some restrictions:

• The Service Broker doesn't store any user credentials so it is not possible to get information about a service key. In contrast to to Cloud Foundry CLI the sb create-service-key returns the credentials.
• The Service Broker also doesn't store any information about the real service names. The broker only works with UUIDs.

Target and login

Use sb target to target a Service Broker.

$ sb target https://localhost:3001

SB CLI supports TLS encrypted communication. To login you can use either sb login as an interactive operation or sb auth for scripting.

sb login also supports the flags -a for API, -u for the username and -p for the password. So you can use

$sb login -a https://redis-broker.service.dc1.consul.dsf2:3001 -u admin -p <password>

The credentials will be stored in JSON format in the file .sb. Those files can be located either in the current working directory or in its parent directory. If the file was not found, sb is looking also in the users root path.

--> /some/where/on/your/disk
--> /some/where/on/your
--> /some/where/on
--> /some/where
--> /some
--> /
--> ~

Alternative Way to Use the CLI

The Service-Broker-CLI is able to read the credentials and the host from environment variables. No login is then needed.

$ SB_HOST="http://redis-service-broker.service.dc1.consul:3000/" SB_USERNAME="admin" SB_PASSWORD="mytopsecretpwd" sb ......

Env Var	Description
SB_HOST	The host name, it can be the IP, the FQHN, with or without the scheme and port
SB_USERNAME	The username
SB_PASSWORD	The password
SB_SKIP_SSL_VERIFY	If true SSL verification is skipped
SB_TIMEOUT	HTTP Timeout in seconds (default: 15)

Logging

Service-Broker-CLI does not provide a logging in the classical sense. But you can trace the Service Broker API requests and answers.

$ SB_TRACE=ON && sb services
