ansible:Failed to connect to the host via ssh: Warning: Permanently added '10.90.0.2' (ECDSA) to the list of known hosts.\r\nPermission denied - ansible

Question

i want to use the key login some host, but some err happened
my files is this below:
[jenkins#ci-jenkins-slave-dev test]$ ls
ansible.cfg hosts test.yml
my hosts file:
[jenkins#ci-jenkins-slave-dev test]$ cat hosts
[controller]
10.90.0.2 ssh_key_pass=passw0rd ansible_ssh_user=root
my playbook:
[jenkins#ci-jenkins-slave-dev test]$ cat test.yml
---
- name: test
hosts: controller
tasks:
- name: add key
authorized_key:
user: root
key: "{{ lookup('file', '~/.ssh/id_rsa.pub') }}"
when run playbook :
[jenkins#ci-jenkins-slave-dev test]$ ansible-playbook test.yml
PLAY [test] ******************************************************************************************************************************************************************************************************************************************************************

I can use "ssh root#10.90.0.2 "and input "passw0rd" to login but ansible can't ,i want to know what's wrong ？

Answer 1

I also faced the same problem. I missed a step.
ssh-copy-id localhost
Then you can successfully run,
ansible-playbook -i hosts simple-docker-project.yml --check

Answer 2

The variable for password is ansible_ssh_pass, but you use ssh_key_pass.
Try with this inventory:
[controller]
10.90.0.2 ansible_ssh_pass=passw0rd ansible_ssh_user=root
