ansible load zshenv and use ENV in another task - ansible

Question

I'd like to load a zshenv file (using source command) and then use the ENVs in another task.
This is what I have. I'm hoping there's a better solution

export XDG_CONFIG_HOME="$HOME/.config"
export GIT_CONFIG_PATH="$XDG_CONFIG_HOME/git/config"
command to run
ansible-playbook profiles/macos.yaml -v
PS: It'd be easier to do something like this in ansible
source tools/zsh/.zshenv && ansible-playbook profiles/macos.yaml -v

Answer 1

Given the simplified project without a role
shell> tree -a .
.
├── ansible.cfg
├── hosts
├── pb.yml
└── tools
├── git
└── zsh
└── .zshenv
shell> cat hosts
localhost
shell> cat tools/zsh/.zshenv
export GIT_CONFIG_PATH=/home/admin/git/.gitconfig
export ENV1=env1
export ENV2=env2
export ENV3=env3
eval "$(direnv hook zsh)"
Parse the environment on your own. For example
zshenv: "{{ dict(lookup('file', 'tools/zsh/.zshenv').splitlines()|
select('match', '^\\s*export .*$')|
map('regex_replace', '^\\s*export\\s+', '')|
map('split', '=')) }}"
gives
zshenv:
ENV1: env1
ENV2: env2
ENV3: env3
GIT_CONFIG_PATH: /home/admin/git/.gitconfig
Then, use the dictionary zshenv
- name: Link gitconfig file
file:
dest: "{{ playbook_dir }}/tools/git/.gitconfig"
src: "{{ zshenv.GIT_CONFIG_PATH }}"
state: link
gives, running with --check -- diff options
TASK [Link gitconfig file] *******************************************************************
--- before
+++ after
## -1,2 +1,2 ##
path: /export/scratch/tmp7/test-116/tools/git/.gitconfig
-state: absent
+state: link
changed: [localhost]
Notes
Example of a complete playbook for testing
shell> cat pb.yml
- hosts: localhost
vars:
zshenv: "{{ dict(lookup('file', 'tools/zsh/.zshenv').splitlines()|
select('match', '^\\s*export .*$')|
map('regex_replace', '^\\s*export\\s+', '')|
map('split', '=')) }}"
tasks:
- debug:
var: zshenv
- name: Link gitconfig file
file:
dest: "{{ playbook_dir }}/tools/git/.gitconfig"
src: "{{ zshenv.GIT_CONFIG_PATH }}"
state: link
gives
shell> ansible-playbook pb.yml
PLAY [localhost] *****************************************************************************
TASK [debug] *********************************************************************************
ok: [localhost] =>
zshenv:
ENV1: env1
ENV2: env2
ENV3: env3
GIT_CONFIG_PATH: /home/admin/git/.gitconfig
TASK [Link gitconfig file] *******************************************************************
changed: [localhost]
PLAY RECAP ***********************************************************************************
localhost: ok=2 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
The link tools/git/.gitconfig -> /home/admin/git/.gitconfig was created
shell> tree -a .
.
├── ansible.cfg
├── hosts
├── pb.yml
└── tools
├── git
│   └── .gitconfig -> /home/admin/git/.gitconfig
└── zsh
└── .zshenv
You can use the dictionary zshenv to set the environment. For example,
- command: echo $GIT_CONFIG_PATH
environment: "{{ zshenv }}"
register: out
- debug:
var: out.stdout
gives
out.stdout: /home/admin/git/.gitconfig
Cache the dictionary if you want to use this environment globally in the whole play. For example,
shell> grep fact_caching ansible.cfg
fact_caching = jsonfile
fact_caching_connection = /tmp/ansible_cache
fact_caching_prefix = ansible_facts_
fact_caching_timeout = 86400
- set_fact:
zshenv: "{{ dict(lookup('file', 'tools/zsh/.zshenv').splitlines()|
select('match', '^\\s*export .*$')|
map('regex_replace', '^\\s*export\\s+', '')|
map('split', '=')) }}"
cacheable: true
Then,
- hosts: localhost
environment: "{{ zshenv }}"
tasks:
- command: echo $GIT_CONFIG_PATH
register: out
- debug:
var: out.stdout
gives
PLAY [localhost] *****************************************************************************
TASK [command] *******************************************************************************
changed: [localhost]
TASK [debug] *********************************************************************************
ok: [localhost] =>
out.stdout: /home/admin/git/.gitconfig
PLAY RECAP ***********************************************************************************
localhost: ok=7 changed=2 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

With the help from Vladimir Botka, using the answer from https://stackoverflow.com/a/74924664/3053548
I modified a little bit of his code
TLDR
source the zshenv file
print out all the ENV in the shell session
store the output to as ansible facts
access the ENV in a task
Files
./profiles/macos.yaml

shell:
cmd: source ../tools/zsh/.zshenv; env

set_fact:
zshenv: "{{ dict(out.stdout.splitlines() | map('split', '=')) }}"
