Re: Can Docker/Artanis run on a network server?

[Mortimer Cladwell]

Hi Nala,

I downloaded and installed the main branch of artanis, reinitialized the database, after a few logins over a couple of days I look at the sessions table:

               sid                | data |            expires            |   client  
----------------------------------+------+-------------------------------+------------
 9999999999                       |      | Sat, 31 Oct 2020 13:41:27 GMT |

One caveat though, I do not let "art work" create the sessions table.  I have my own initialization script that creates the table, and initializes a fake session #1 (sid=9999...) which is required for the creation of many other objects in the database, which all must be associated with a sid upon creation. This is how I bootstrap the app. I changed the CREATE TABLE sessions command in my init script to mimic yours in this new version :

create table if not exists Sessions (sid varchar(32)  ,data text  ,expires varchar(29)  ,client varchar(39)  ,PRIMARY KEY (sid)) ;

So given that caveat it seems to be working, though client is Unknown IP for a locally running dockerized (both client and server) app.  If I move the dockerized server to a remote LAN machine and run undockerized artanis/myapp on my local workstation - still get Unknown IP.


               sid                | data |            expires            |   client

Hi Mortimer!
I've removed the useless valid field in session.
Could you try the vanilla master to test you current case?

If everything is OK, then I think it's time to release 0.5.1 ;-)

Best regards.
