• pip (will not installed)
• python (will be installed)

Variables

• supervisor_version [default: latest]: Supervisor version to install (e.g. latest, 3.1.3)

• supervisor_state [default: started]: Describes the desired state for the supervisor service to be in (e.g. started, stopped)

• supervisor_unix_http_server_file [default: /var/run/supervisor.sock]: A path to a UNIX domain socket (e.g. /tmp/supervisord.sock) on which supervisor will listen for HTTP/XML-RPC requests. supervisorctl uses XML-RPC to communicate with supervisord over this port

• supervisor_unix_http_server_chmod [default: '0700']: Change the UNIX permission mode bits of the UNIX domain socket to this value at startup

• supervisor_inet_http_server_enabled [default: false]: Whether or not to enable the HTTP server

• supervisor_inet_http_server_port [default: 9001]: A TCP host:port value or (e.g. 127.0.0.1:9001) on which supervisor will listen for HTTP/XML-RPC requests. supervisorctl will use XML-RPC to communicate with supervisord over this port

• supervisor_inet_http_server_username [default: admin]: The username required for authentication to this HTTP server Make sure to change!

• supervisor_inet_http_server_password [default: '4ubA&Et=ASPe']: The password required for authentication to this HTTP server. This can be a cleartext password, or can be specified as a SHA-1 hash if prefixed by the string {SHA} Make sure to change!

• supervisor_supervisord_logfile [default: /var/log/supervisor/supervisord.log]: The path to the activity log of the supervisord process

• supervisor_supervisord_pidfile [default: /var/run/supervisord.pid]: The location in which supervisord keeps its pid file

• supervisor_supervisord_childlogdir [default: /var/log/supervisor]: The directory used for AUTO child log files

• supervisor_supervisorctl_serverurl [default: "unix://{{ supervisor_unix_http_server_file }}"]: The URL that should be used to access the supervisord server, e.g. http://localhost:9001. For UNIX domain sockets, use unix:///absolute/path/to/file.sock

• supervisor_include [default: '/etc/supervisor/conf.d/*.conf']: A (single) absolute file glob of files to include

• supervisor_programs_present [default: {}, see templates/etc/supervisor/conf.d/program.conf.j2]: Program definitions

• supervisor_programs_present.{n} [required]: Program name

• supervisor_programs_present.{n}.command [required]: The command that will be run when this program is started

• supervisor_programs_present.{n}.directory [optional]: A directory to which supervisord should temporarily chdir before exec’ing the child

• supervisor_programs_present.{n}.environment [optional]: A list of key/value pairs that will be placed in the child process’ environment

• supervisor_programs_present.{n}.autostart [optional]: If true, this program will start automatically when supervisord is started

• supervisor_programs_present.{n}.autorestart [optional]: Whether the process will be autorestarted

• supervisor_programs_present.{n}.startretries [optional]: The number of serial failure attempts that supervisord will allow when attempting to start the program before giving up

• supervisor_programs_present.{n}.stdout_logfile [optional]: Put process stdout output in this file

• supervisor_programs_present.{n}.stdout_logfile_maxbytes [optional]: The maximum number of bytes that may be consumed by stdout_logfile before it is rotated

• supervisor_programs_present.{n}.stderr_logfile [optional]: Put process stderr output in this file

• supervisor_programs_present.{n}.stderr_logfile_maxbytes [optional]: The maximum number of bytes before logfile rotation for stderr_logfile

• supervisor_programs_present.{n}.user [optional]: This UNIX user account will be used as the account which runs the program

• supervisor_programs_present.{n}.numprocs [optional]: Supervisor will start as many instances of this program as named by numprocs

• supervisor_programs_present.{n}.process_name [optional]: Process name, defaults to %(program_name)s-%(process_num)s when numprocs > 1

• supervisor_programs_present.{n}.stopsignal [optional]: The signal used to kill the program when a stop is requested

• supervisor_programs_present.{n}.stopwaitsecs [optional]: The number of seconds to wait for the OS to return a SIGCHILD to supervisord after the program has been sent a stopsignal

• supervisor_programs_present.{n}.stopasgroup [optional]: If true, the flag causes supervisor to send the stop signal to the whole process group and implies killasgroup is true

• supervisor_programs_present.{n}.killasgroup [optional]: If true, when resorting to send SIGKILL to the program to terminate it send it to its whole process group instead, taking care of its children as well

• supervisor_programs_absent [default: {}]: Program definitions (to be removed)

• supervisor_groups_present [default: {}, see templates/etc/supervisor/conf.d/group.conf.j2]: Group definitions

• supervisor_groups_present.{n} [required]: Group name

• supervisor_groups_present.{n}.programs [required]: List of programs

• supervisor_groups_present.{n}.priority [optional]: A priority number

• supervisor_groups_absent [default: {}]: Group definitions (to be removed)

Dependencies

None

Recommended

• ansible-pip (see)

Example

---
- hosts: all
  roles:
    - supervisor

Adding two programs in one group

supervisor_programs_present:
  foo:
    command: 'sleep 10'
    directory: /tmp
    autostart: true
    autorestart: true
    startretries: 3
    stdout_logfile: /tmp/foo.out
    stdout_logfile_maxbytes: 0
    stderr_logfile: /tmp/foo.err
    stderr_logfile_maxbytes: 0
    user: vagrant
    numprocs: 8
    process_name: %(program_name)s-%(process_num)s
  bar:
    command: 'sleep 10'
    directory: /tmp
    autostart: true
    autorestart: true
    startretries: 3
    stdout_logfile: /tmp/bar.out
    stdout_logfile_maxbytes: 0
    stderr_logfile: /tmp/bar.err
    stderr_logfile_maxbytes: 0
    user: vboxadd

supervisor_groups_present:
  foo-and-bar:
    programs:
      - foo
      - bar
    priority: 10

Removing a group

supervisor_groups_absent:
  foo-and-bar: {}
