Hi

Thanks for using ansible. To answer your question more information is
needed. Could you please describe clearly all of the below:

- Which commands did you run, and what actual output did you get
(copied as plain text - not as screenshots, images, or other binary
attachments).
- What do the relevant inventory/tasks/playbooks/code/variables look like.
- The output of ‘ansible --version’

Command : ansible-playbook elk-playbook.yml

[root@localmain .ansible]#

elk-playbook has two tasks,

ping and include role tes.elasticsearch

ansible version :

[root@localmain .ansible]# ansible --version
ansible 2.9.3
config file = /etc/ansible/ansible.cfg
configured module search path = [‘/root/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’]
ansible python module location = /usr/lib/python3.6/site-packages/ansible
executable location = /usr/bin/ansible
python version = 3.6.8 (default, Nov 21 2019, 19:31:34) [GCC 8.3.1 20190507 (Red Hat 8.3.1-4)]
[root@localmain .ansible]#

Curl to the key url works on localmain(control) as well as localhost1(node)
Checked the proxy too, included proxy var in /etc/profile.d/proxy.sh

what else i missed? am not aware

Found a way through setting up

my proxy under environment: in ansible playbook,

now facing this error

FAILED! => {“changed”: false, “msg”: “Failed to download packages: Cannot download 7.6.1/elasticsearch-7.6.1-x86_64.rpm: All mirrors were tried”, “results”: }

any clue to this?

Hii

followed few help from this link https://access.redhat.com/discussions/4222851#comment-1751291 like dnf upgrade -y --releasever=8

after that on first run of

ansible-playbook -vvv --flush-cache elk-playbook.yml

Escalation succeeded

I'm not going to waste more of my time by having information spoon fed
like this.
We're done.

anyhow newbie communication makes bad,

tried setting up a new vm tried a fresh ansible-playbook run on the vm, still getting the same error

dunno where it falls

10

It sounds like you require a network proxy but haven’t configured dnf to use it correctly. See https://unix.stackexchange.com/a/436562/249351

Hi Nick,

I did add the proxy to the vars in elk-playbook.yml ,

Accessing through ansible only fails

The below is my ansible section, where am doing the test

The actual ansible error is
