ansible "sed: can't read file: No such file or directory"

Question

I have an Ansible playbook that should execute a script. This Script should add lines of code to a file. Note that the playbook is bigger then this one role though all other steps of the ansible-playbook work. The script also works when executed directly on the puppet server. I suspect that it is a permissions issue, though i am not sure how to solve the problem.

Note: The ansible playbook is getting executed as ansible user. The script and the file with the added lines are owned by usr ansible and grp ansible. Rights are: 0755. The file to be changed is also at the same location as the script.

script name:

createlines.sh

file with the added lines:

testfile.py

hosts:

puppet

ansible command:

ansible-playbook deployment-test.yml --ask-become-pass

playbook:

---
- name: add lines in file
  hosts: Puppet
  become: yes
  become_method: sudo
  become_user: root
  vars_files:
    - vars/gpv-test.yml
  roles:
    - run-script

roles/run-script:

---
- name: Execute the createlines script
  command: sh /var/opt/alu/deploy/hieradata/createlines.sh

Error message(is extremly big and constantly repeats itself):

Start of error message:

End of error message:

Does someone see what could be wrong?

testfile.py:

"some Python code(not relevant)"
trm_data_files:
"Place where lines get inserted"
"some Python code(not relevant)"

Answer 1

Please make sure that you are using the full path to the testfile.py script in your shell script. When Ansible runs shell commands, it does this from a different location, e.g. the /tmp directory. Using the full, absolute path to your Python script will ensure that it can be found in this case.

You can run Ansible with the -vvv parameter to see the location of the script when it gets executed by Ansible.

Answer 2

the createlines.sh seems to be present on targeted host but not the py file.

you should ensure that the py file is either copied and present on the target host.
