Hi,
I know the solution to this topic has been posted many times and I have
tried searching through google and other forums including the ansible docs
but unfortunately, nothing seems to be working for me. Please provide your
feedback and help me with the solution. Also please let me know if you need
any further information.
I am trying to create a playbook to download and install jenkins from a war
file and so installing java from the source file as a pre-requisite.
I check for the presence of Java and if not found, go on to download and
install java from source and then registering the env variable JAVA_HOME
and adding the java binary onto my PATH. However, the environment variable
part is frustratingly not working for me.
I initially started out with using the shell module to source /etc/profile
using /bin/bash, but that didnt work. Read more and found out about
environment keyword. As part of my playbook, I create a user jenkins_user
and then download the jenkins war file and try to run with the above
defined env variables. unfortunately, it is not working. However, I am not
sure I am doing this the correct way as I keep getting failures and the
latest is that 'java' cannot be found by newly created jenkins_user.
Pasted below is all my code.
