How set 2 environment (PATH and proxy_env ) in ansible-playbook?

[Антон Пацев]

Hello!

Trying to install run ansible-playbook (kubespray) through a proxy.

Here specify the proxy server: https://github.com/kubernetes-incubator/kubespray/blob/master/inventory/sample/group_vars/all/all.yml#L52

Added to the longing Install packages requirements for bootstrap

environment: "{{proxy_env}}"

https://github.com/kubernetes-incubator/kubespray/blob/master/roles/bootstrap-os/tasks/bootstrap-centos.yml#L24

Throws an error

Trying other mirror.

If a yaml file to do this task

- name: echo Variables
  shell: "echo $http_proxy $https_proxy"
  register: shell_echo_proxy
  environment: "{{proxy_env}}"

- debug:
    var: shell_echo_proxy.stdout

The will here is such a mistake:

The field 'environment' has an invalid value, which includes an undefined variable. The error was: 'ansible.vars.hostvars.HostVarsVars object' has no attribute 'ansible_default_ipv4'

The error appears to have been in '/home/user/kubespray/roles/bootstrap-os/tasks/bootstrap-centos.yml': line 17, column 3, but may
be elsewhere in the file depending on the exact syntax problem.


The offending line appears to be:

- name: echo Variables
  ^ here

Try other code

- name: echo Variables

  shell: "echo $http_proxy $https_proxy"

  register: shell_echo_proxy

  environment:

    - PATH: "/sbin:/usr/sbin:{{ ansible_env.PATH }}"

    "{{proxy_env}}"

- debug:

    var: shell_echo_proxy.stdout
