Thanks *Rad* Gruchalski, actually i'm trying to make a json file that "translate" this command in marathon:
docker run --name some-wordpress --link some-mysql:mysql -d wordpress i guess the error is relate to the fact that i'm not specifying --link some-mysql:mysql My problem is that i don't know how to do that, i tried to fill environment variable fields: Key = link Value = some-mysql:mysql But in this way the app does not work as well. How can i configure these env variables? 2016-04-26 16:01 GMT+02:00 Rad Gruchalski <[email protected]>: > It says exactly what the problem is. > > Start a marathon task with correct environment variables in env and you > will be fine. > > Best regards, > Radek Gruchalski > [email protected] <[email protected]> > de.linkedin.com/in/radgruchalski/ > > > *Confidentiality:*This communication is intended for the above-named > person and may be confidential and/or legally privileged. > If it has come to you in error you must take no action based on it, nor > must you copy or show it to anyone; please delete/destroy and inform the > sender immediately. > > On Tuesday, 26 April 2016 at 15:56, Stefano Bianchi wrote: > > jupyter is working fine. > i tried to run wordpress and i get this error in stderr of mesos: > > error: missing WORDPRESS_DB_HOST and MYSQL_PORT_3306_TCP environment > variables > > Did you forget to --link some_mysql_container:mysql or set an external db > > with -e WORDPRESS_DB_HOST=hostname:port? > > > > Some one of you know this issue? > > > > > > > > > > > > > 2016-04-26 15:51 GMT+02:00 Stefano Bianchi <[email protected]>: > > However thank you so much to all! > > 2016-04-26 15:22 GMT+02:00 Stefano Bianchi <[email protected]>: > > i found the answer by my self sorry if i disturbed you. > > 2016-04-26 15:19 GMT+02:00 Stefano Bianchi <[email protected]>: > > Now that it is running, how can i check the User Interface? > > > 2016-04-26 15:18 GMT+02:00 Stefano Bianchi <[email protected]>: > > Yes, now it's running!!!
