Ansible installation has all necessary parameters for connecting to managed hosts. Duplicationg this parameters in ~/.ssh/config is not convenient, especially if dynamic inventory is used.
This script parses ansible configuration to get that parameters. Just place it somewhere in your $PATH, like ~/.local/bin.
Considered inventory variables: ansible_host, ansible_ssh_host, ansible_user, ansible_ssh_user, ansible_port, ansible_ssh_port,ansible_ssh_private_key_file, ansible_ssh_common_args.
Considered configuration variables: ssh_args.
How it works:
user@work$ cd my_ansible_repo
user@work$ cat hosts | grep server1
server1 ansible_host=192.168.0.1 ansible_user=ubuntu ansible_port=2222
user@work$ cat ansible.cfg | grep ssh_args
ssh_args = -C -o ControlMaster=auto -o ControlPersist=60s
user@work$ ./ssh-ansible server1
ssh_args: -C -o ControlMaster=auto -o ControlPersist=60s
ansible_host: 192.168.0.1
ansible_user: ubuntu
ansible_port: 2222
ansible_ssh_common_args:
result command: ssh ubuntu@192.168.0.1 -C -o ControlMaster=auto -o ControlPersist=60s -p 2222
