tomcatmanager 0.10.0

A command line tool and python library for managing a tomcat server.

If you use Apache Tomcat for any sort of development work you’ve probably deployed lots of applications to it. There are a several ways to get your war files deployed:

• use the Tomcat Manager application in your browser

• use the Tomcat Ant Tasks included with Tomcat

• use Cargo and its plugins for ant and maven

Here’s another way: a command line tool and python library for managing a Tomcat server.

What Can It Do?

This package installs a command line utility called tomcat-manager. It’s easily scriptable using your favorite shell:

$ tomcat-manager --user=ace --password=newenglandclamchowder \
http://localhost:8080/manager deploy local sample.war /sampleapp
$ echo $?
0

There is also an interactive mode:

$ tomcat-manager
tomcat-manager>connect http://localhost:8080/manager ace newenglandclamchowder
tomcat-manager>list
Path                     Status  Sessions Directory
------------------------ ------- -------- ------------------------------------
/                        running        0 ROOT
/sampleapp               stopped        0 sampleapp##9
/sampleapp               running        0 sampleapp##8
/host-manager            running        0 /usr/share/tomcat8-admin/host-manage
/manager                 running        0 /usr/share/tomcat8-admin/manager

And for the ultimate in flexibility, you can use the python package directly:

>>> import tomcatmanager as tm
>>> tomcat = tm.TomcatManager(url='http://localhost:8080/manager',
... userid='ace', password='newenglandclamchowder')
>>> tomcat.is_connected
True
>>> r = tomcat.stop('/someapp')
>>> r.status_code == tm.codes.ok
False
>>> r.status_message
'No context exists named /someapp'

Installation

You’ll need Python >= 3.4. Install using pip:

$ pip install tomcatmanager

Works on Windows, macOS, and Linux.

Tomcat Configuration

This library and associated tools do their work via the Tomcat Manager web application included in the Tomcat distribution. You will need to configure authentication in tomcat-users.xml with access to the manager-script role:

<tomcat-users>
.....
  <role rolename="manager-script"/>
  <user username="ace" password="newenglandclamchowder" roles="manager-script"/>
</tomcat-users>
