Last week I wrote an article about creating offline update repository for VMware virtual appliances and demonstrating the use of the VAMI web interface for updating and upgrading a VMware virtual appliance. However, from an automation perspective, the web interface is probably not the right tool for the job and this where the vamcli can help.

Usage: vamicli [options]
may be:
network          Network Configuration
update           Update Management
version          Version Information
service          Service Management

Use vamicli to see a list of options.

The vamicli is a command-line tool that is available on all virtual appliances built using VMware Studio and it provides a subset of the functionality of the VAMI web interface. Using the "update" operation, you can check for available updates as well as performing the installation of an update.

To check for the latest update just like you would using the VAMI web interface, you would run the following command:

vamicli update --check

To install the latest update, you would run the following command:

vamicli update --install latest --accepteula

Here is a screenshot example of going through both of these commands on a VIN 1.2 virtual appliance and then upgrading to VIN 2.0:

As you can see the process is pretty straight forward and this allows you to easily automate the updates of your virtual appliances without having to resort to the VAMI web interface.

For those of you who read my previous article and wish to configure a custom update repository without using the VAMI web interface, you can add the following configuration to /opt/vmware/var/lib/vami/update/provider/provider-runtime.xml where value specifies the HTTP address to your update repository as you would configure using the VAMI web interface.

If you would like to configure additional authentication properties such as username and password, then the /opt/vmware/var/lib/vami/update/provider/provider-runtime.xml should look like the following: The password value is encoded using base64, so to generate the encoding you can use the following python snippet (where password is the password you wish to encode:

python -c "import base64; print base64.b64encode('password')"

Note: The configuration changes above go into effect immediately and you can then use vamicli to perform both check and install operations.
