Remote API for docker exec commands

Question

Could someone please help me with remote api for docker exec to run a command?

I am able to run it directly:

# docker exec 941430a3060c date
Fri Apr

You have to follow below steps. I am adding rest api way. You can code it to any language.

1. EXEC CREATE

POST /containers/(id or name)/exec

Body

{
  "AttachStdin": false,
  "AttachStdout": true,
  "AttachStderr": true,
  "Cmd": ["bash","-c","echo '*/5 * * * * /usr/bin/php /app/yii cronrun/job001'>> /var/spool/cron/crontabs/root"]
}

You have to select Content-Type: application/json

when you POST the above data you will get id in response. You have to use the id in next step.

*The above will add cron job in container which will execute every five minute.

2. EXEC START

POST /exec/(id)/start

{
 "Detach": false,
 "Tty": false
}

You have to select Content-Type: application/json

Check response code, 200 is OK
