You can access the Theia using the url and logging in with username and password.

Locate instance_html5as.cfg.in to add title parameter.

Add title into [publish-connection-information], so it can be published while inspecting the connection parameters.

title = Title ${slap-parameter:title}! 

Add [slap-parameter] section with title, so we can customize the title while requesting the instance.

[slap-parameter]
title =

Any buildout.cfg files downloaded by Buildout must have a corresponding MD5 sum. This is done for security and to enforce strict stability of the software release overtime.

Since we modified intance_html5as.cfg.in to have a title parameter, the MD5 sum should be updated to software.cfg.

After located intance_html5as.cfg ($ cd ~/srv/project/slapos/software/html5as-base/), you can run:

$ md5sum instance_html5as.cfg.in

to get MD5 sum of the file. Then copy the hash into [instance_html5as] section in software.cfg to replace the old md5sum.

Since we modified intance_html5as.cfg.in to have a title parameter, the instance will be  re-instantiated by auto-running. You can retrieve the log of slapos node instance following Inspect Logs In Rapid.Space Theia Runner to verify if the the instance is ready: 

$ tail -f ~/srv/runner/var/log/slapos-node-instance.log

Once it's instantiated successfully, you can inspect the connection parameters by rerunning the request script:

$ cd ~/srv/project/slapos/software/html5as-base/
$ bash ../../../request-html5as-base.sh 

The connection parameters with 'title': 'Title couscous!' are expected.

You can also verify the server_url by

$ curl server_url

Hello World! will be displayed. 

To pass on the parameters to the requesting instance, we rely on --parameters key='value' of slapos request command.

Open the request script and add the parameter:

slapos request $software_name'_1' $software_release_uri --parameters title='John Doe'

Make sure to edit it in your request file instead of the example one. 

To pass on the parameter, we are supposed to request the instance again by rerunning the request script:

$ cd ~/srv/project/slapos/software/html5as-base/
$ bash ../../../request-html5as-base.sh 

As you can see, the connection parameters are still the previous ones, because to apply the modification, the instance will be re-instantiated by auto-running.  You can retrieve the log of slapos node instance following Inspect Logs In Rapid.Space Theia Runner to verify if the the instance is ready: 

$ tail -f ~/srv/runner/var/log/slapos-node-instance.log

To inspect the modification of connection parameters, we are supposed to run the requesting script again:

$ cd ~/srv/project/slapos/software/html5as-base/
$ bash ../../../request-html5as-base.sh 

As you can see from the output,  the value of 'title' parameter has been changed form 'Title couscous!' to 'Title John Doe!'.

You can also verify the server_url by curl: 

curl server_url

Hello World! will be displayed.
