Upgrading Supervisor 2 to 3
The following is true when upgrading an installation from Supervisor 2.X to Supervisor 3.X:
[program:x]sections, the keys
log_stdoutare no longer valid. Supervisor2 logged both stderr and stdout to a single log file. Supervisor 3 logs stderr and stdout to separate log files. You'll need to rename
stdout_logfile_maxbytesat the very least to preserve your configuration. If you created program sections where
log_stderrwas true, to preserve the behavior of sending stderr output to the stdout log, use the
redirect_stderrboolean in the program section instead.
The supervisor configuration file must include the following section verbatim for the XML-RPC interface (and thus the web interface and :program:`supervisorctl`) to work properly:
[rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
The semantics of the
[program:x]sections has changed. This parameter used to accept only
false. It now accepts an additional value,
unexpected, which indicates that the process should restart from the
EXITEDstate only if its exit code does not match any of those represented by the
exitcodeparameter in the process' configuration (implying a process crash). In addition, the default for
unexpected(it used to be
true, which meant restart unconditionally).
We now allow :program:`supervisord` to listen on both a UNIX domain socket and an inet socket instead of making listening on one mutually exclusive with listening on the other. As a result, the options
sockchownare no longer part of the
[supervisord]section configuration. These have been supplanted by two other sections:
[inet_http_server]. You'll need to insert one or the other (depending on whether you want to listen on a UNIX domain socket or a TCP socket respectively) or both into your :file:`supervisord.conf` file. These sections have their own options (where applicable) for
All supervisord command-line options related to
sockchownhave been removed (see above point for rationale).
The option that used to be
[supervisord]section (and is now named
[unix_http_server]section) used to accept a dot-separated (
user.group) value. The separator now must be a colon, e.g.
user:group. Unices allow for dots in usernames, so this change is a bugfix.
