Vincent Sesto - Practical Ansible_ Configuration Management from Start to Finish-Apress (2021)
1. build a Linux server that has ssh service available
reference from: https://dev.to/s1ntaxe770r/how-to-setup-ssh-within-a-docker-container-i5i
# Dockerfile
FROM ubuntu:latest
RUN apt update && apt install openssh-server sudo -y
RUN useradd -rm -d /home/ubuntu -s /bin/bash -g root -G sudo -u 1000 test
RUN echo 'test:test' | chpasswd
RUN service ssh start
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]
build
sudo docker build -t sshd .
use
sudo docker run --name sshd -p 2222:22 -d sshd
stop
sudo docker stop sshd
sudo docker rm sshd
connect
ssh-copy-id test@127.0.0.1 -p 2222
ssh test@127.0.0.1 -p 2222
#password is 'test'
2. use ansible to run commands over your server
configuration
# inventory
[App1]
127.0.0.1:2222
[App1:vars]
ansible_connection=ssh
ansible_user=test
ansible_ssh_pass=test
ansible_sudo_pass=tes
# test.yml
---
- name: My task 1
hosts: App1
tasks:
- name: print out who you are, test
remote_user: test
command: "/bin/whoami"
- name: print out who you are, root
remote_user: test
command: "/bin/whoami"
become: true
usage
ansible all -i inventory -u test -m ping
ansible all -i inventory -u test -a "/bin/echo hello"
ansible-playbook -i inventory test.yml -v
