I tried to start a CloudSQL proxy on supervisor, however I have no idea what is wrong with it. The documentation does not show any clues to this issue. Any ideas would be much appreciated.
I tried the setup on a clean Ubuntu 16 and then installed supervisor and downloaded cloud_sql_proxy. And I put files under /root and execute as root for debugging.
Here is my current setup:
/etc/supervisord.conf
[unix_http_server]
file=/tmp/supervisor.sock ; the path to the socket file
chmod=0766 ; socket file mode (default 0700)
[supervisord]
logfile=/tmp/supervisord.log ; main log file; default $CWD/supervisord.log
logfile_maxbytes=50MB ; max main logfile bytes b4 rotation; default 50MB
logfile_backups=10 ; # of main logfile backups; 0 means none, default 10
loglevel=info ; log level; default info; others: debug,warn,trace
pidfile=/tmp/supervisord.pid ; supervisord pidfile; default supervisord.pid
nodaemon=false ; start in foreground if true; default false
minfds=1024 ; min. avail startup file descriptors; default 1024
minprocs=200 ; min. avail process descriptors;default 200
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket
[include]
files = /etc/supervisor/conf.d/*.conf
/etc/supervisor/conf.d/cloud_sql_proxy.conf
[program:cloud_sql_proxy]
command=/root/cloud_sql_proxy -dir=/cloudsql -instances="project_id:us-central1:instance-name" -credential_file="/root/service-account.json"
autostart=true
autorestart=true
startretries=1
startsecs=8
stdout_logfile=/var/log/cloud_sql_proxy-stdout.log
stderr_logfile=/var/log/cloud_sql_proxy-stderr.log
I got the following error after inspecting /tmp/supervisord.log:
2018-10-14 15:49:49,984 INFO spawned: 'cloud_sql_proxy' with pid 3569

2018-10-14 15:51:47,999 INFO gave up: cloud_sql_proxy entered FATAL state, too many start retries too quickly
Finally I managed to figure out a working solution, and here is it:
Create a new file /root/start_cloud_sql_proxy.sh:
#!/bin/bash
/root/cloud_sql_proxy -dir=/cloudsql -instances="project_id:us-central1:instance-name" -credential_file="/root/service-account.json"
Under /etc/supervisor/conf.d/cloud_sql_proxy.conf, change the command to execute a bash file:
command=/root/start_cloud_sql_proxy.sh
