kubectl 完成 bash 与 Ancible

Question

I am new to ansible, please bear with me.

I have the following shell commands for bash completion.

I want to achieve that with Ansible.

apt-get install net-tools bash-completion -y
kubectl completion bash >/etc/bash_completion.d/kubectl
echo 'source <(kubectl completion bash)' >> /etc/bashrc

I am stuck with the middle one. The first and last I know how to write in Ansible.

kubectl completion bash >/etc/bash_completion.d/kubectl

Basically as I understand(I am new to bash scripting as well) the output to the command

kubectl completion bash 

should be written to the file /etc/bash_completion.d/kubectl

It should be simple I guess. If some one can nudge me in the right direction, it would be helpful.

Answer 1

The Ansible command module will not work, as stated in the doc:

The command(s) will not be processed through the shell, so variables like $HOSTNAME and operations like "*", "<", ">", "|", ";"and "&" will not work.

You should rather take a look at Ansible shell module , especially the examples provided.

Something like this should do the trick:

- name: Execute the command in remote shell and write the output in the specified remote file
  ansible.builtin.shell:
    cmd: kubectl completion bash > /etc/bash_completion.d/kubectl
    # If you do not want to run this when the file already exists, add
    creates: /etc/bash_completion.d/kubectl
