VisualizaçõesHold multiple packages using Ansible
I am trying to hold multiple packages using ansible-playbook but it doesn't work with me.
Using the below code it holds the first package then un-hold it then hold the second package
Here is my code
- name: Prevent packages from being upgraded
dpkg_selections:
name: "{{ item }}"
selection: hold
with_items:
- postgresql
- docker
Here is the output from the server side while the code executing
the first line before executing
the second line is the output when the first package was hold
the third line when the second package was held and it is stoped
I don't understand why the behavior is like that? and how can I hold multiple packages at a time using ansible?
NOTE: I already followed the instruction from Anible doc https://docs.ansible.com/ansible/latest/collections/ansible/builtin/dpkg_selections_module.html Thanks in advance

Already for performance and resource reasons, providing the packages as list might be better.
- name: Prevent packages from being upgraded
dpkg_selections:
name: ['postgresql', 'docker']
selection: hold
However, your test reported
dpkg: error: unexpected data after package and selection
Therefore it might be that the module can't handle lists, so I had a look into the source dpkg_selections.py. It seems to be a somehow simple wrapper
module.run_command([dpkg, '--set-selections'], data="%s %s" % (name, selection), check_rc=True)
which just provide information for one module. I also assume the module should work with_items, but it seems to be not the case because of your question.
According man pages, the command dpkg itself seems to be able to handle a package list, but provided as character separated value file
dpkg --set-selections < /tmp/pkg_list
with delimiter in the format
postgresql hold
docker hold
A simple workaround could help in your case.
- name: Prevent packages from being upgraded
shell:
cmd: |
dpkg --set-selections << EOF
postgresql hold
docker hold
EOF
warn: false
register: result
You may need to implement some error and status handling by yourself, i.e.
changed_when: result.rc ...
failed_when: result.rc ...

What about:
- name: Prevent packages from being upgraded
dpkg_selections:
name: "{{ item }}"
selection: hold
loop:
- postgresql
- docker
In my case, the output from the server side after the execution was the full list of packages.
