Apply manifests on Puppet Managed Nodes from Puppet Master and appending to an existing file

[Sivaraman Viswanathan]

Hello All,

I have written a manifest which will upgrade the JAVA to a recent version (ex: JDK 6u33 to JDK7) using exec type. The installation is nothing but untarring the tar.gz file into a predefined folder and setting the JAVA_HOME and PATH variables in the user's bash_profile file.

1. Now I have to upgrade around 30 servers. Is there anyway that I can apply these manifests into the nodes from puppet master itself?

   Many of the examples that I found says that we have to login to the node and execute the command puppet agent update command. But doing this in all the managed nodes is tedious.

   Is there an easy way to accomplish this?

2. The bash_profile contains other text in them. How can we append these new variables (JAVA_HOME) into the existing file without changing the other parts of the file?

Reg,

Siva

You could set up the agent to poll the master periodically.

What I would look at is creating a .java_settings file that sets your
JAVA_* and have that sourced from the .profile. That way you could have
puppet manage that file in its entirety and not the user's .profile.

Yep

You can also use the /etc/profile.d directory which is sourced in
/etc/profile at least on Arch and Ubuntu.

Best, Nikola
