Ansible：如何更改 Ansible Playbook 中的活动目录？

Question

- name: Go to the folder
  command: chdir=/opt/tools/temp

When I run my playbook, I get:

TASK: [Go to the folder] ***************************** 
failed: [host] => {"failed": true, "rc": 256}
msg: no command given

Any help is much appreciated.

Answer 1

There's no concept of current directory in Ansible. You can specify current directory for specific task, like you did in your playbook. The only missing part was the actual command to execute. Try this:

- name: Go to the folder and execute command
  command: chdir=/opt/tools/temp ls

This question was in the results for when I was trying to figure out why 'shell' was not respecting my chdir entries when I had to revert to Ansible 1.9. So I will be posting my solution.

I had

- name: task name
  shell:
    cmd: touch foobar
    creates: foobar
    chdir: /usr/lib/foobar

It worked with Ansible > 2, but for 1.9 I had to change it to.

- name: task name
  shell: touch foobar
  args:
    creates: foobar
    chdir: /usr/lib/foobar

Just wanted to share.

如果你需要一个登录控制台（比如 bundler），那么你必须像这样执行命令。

command: bash -lc "cd /path/to/folder && bundle install"

Answer 4

You can change into a directory before running a command with ansible with chdir .

Here's an example I just setup:

- name: Run a pipenv install
  environment:
    LANG: "en_GB.UTF-8"
  command: "pipenv install --dev"
  args:
    chdir: "{{ dir }}/proj"
