I want to run Rserve (as daemon process) in docker container.My basic requirement is I want to have one R program which will be running as background process. To achieve this i have created one R file and I am trying to run same with Rserve. For this i have created supervisor.conf file with below entry.
[supervisord]
nodaemon=true
[program:rserve]
command=/usr/bin/R CMD Rserve --slave --RS-conf
/sri-app/rserve/rserve.conf --RS-source /sri-app/rserve/rserve-src.R
user=root
autostart=true
autorestart=true
stdout_logfile=/tmp/rserve_out.log
stderr_logfile=/tmp/rserve_err.log
environment=PATH="/usr/bin/R"Below are the entries for "rserve.conf" file
http.port 8080
remote disable
auth disable
daemon enable
control disable
I have included this supervisor.conf entry in dockerfile as below
CMD ["/sri-app/run_supervisord.sh"]
where "run_supervisord.sh" has entries below
#!/bin/bash
/usr/bin/supervisord -c /sri-app/api-supervisor.conf
Now the issue is when I am running docker container facing below error.
2019-11-13 10:39:48,738 INFO supervisord started with pid 102

Any suggestions?
