In its simplest form, deployment with Ansible may consist of copying a single binary to the target machine and then running that binary. We can achieve this with the following Ansible code:
tasks:
# Each Ansible task is written as a YAML object
# This uses a copy module
- name: Copy the binaries to the target machine
copy:
src: our_application
dest: /opt/app/bin/our_application
# This tasks invokes the shell module. The text after the `shell:` key
# will run in a shell on target machine
- name: start our application in detached mode
shell: cd /opt/app/bin; nohup ./our_application </dev/null >/dev/null 2>&1 &
Every single task starts with a hyphen. For each of the tasks, you need to specify the module it uses (such as the copy module or the shell module), along with its parameters (if applicable). A task may also have a name parameter, which makes it easier to reference the task individually.
