az ad sp create-for-rbac --name ansible-sp-dev --role Contributor --scopes /subscriptions/
- Create mkdir ~/.azure
- Edit file ~/.azure/credentials and add below blocks
[default]
subscription_id=?
client_id=?
secret=?
tenant=?
** Generate private and public keys **
- ssh-keygen -m PEM -t rsa -b 2048
- chmod 755 ~/.ssh
- touch ~/.ssh/authorized_keys
- chmod 644 ~/.ssh/authorized_keys
- ssh-copy-id devopsmela@127.0.0.1
- ssh devopsmela@127.0.0.1 {Verify key login}
- cat ~/.ssh/id_rsa {Copy the private key}
** Create SSH Service Connection in Azure DevOps
- paste the private key copied
** Create release pipeline
- Ansible location --> Remote Machine
- Playbook --> Source --> Agent Machine {If playbook and others are part of repositories}

[@Arun_7793]

how kubernetes and secrets manager or vaults are integrated?

[@DevOpsMela]

Will get the topic covered in the next upcoming video’s

[@Kelly-wy2uf]

Thanks good video, but if you want to be great video , 😊you would show how to use in production, ie dont disable host key check. Setup vault all from beginning, just some advice. So many videos show the "lazy" way. Standout by going extra mile

[@DevOpsMela]

Definitely will covers those in my advance topics
