which describes more about the Python S2I image in particular. You can see the 
code there for it as well.

Re: error running python script in openshift

[Graham Dumpleton]

If you want to supply your own way of starting up your application when using 
Python S2I, supply an executable 'app.sh' file.  This should be a shell script 
which runs your application. Ensure that the final application is run using 
'exec'. Eg.

#!/bin/bash

exec python my-custom-app.py

Again point you to:

https://www.openshift.com/deploying-to-openshift/ 


to understand how S2I works.

Re: how to execute a script with S2i in openshift?

[Graham Dumpleton]

As Brian says, use a custom assemble script that calls the original.

For a description of customising the S2I build process, check out the free 
eBook for OpenShift at:

https://www.openshift.com/deploying-to-openshift/ 


Chapter 9 covers this and more.

Re: how to execute a script with S2i in openshift?

[Brian Keyes]

Ok what I will do is rename the app.py to run and change the path in git
hub to be  s2i/bin/run.


I am not sure I understand what you mean by

"Use exec for the call"


thanks again !!

Re: how to execute a script with S2i in openshift?

[Brian Keyes]

thanks for the quick reply ,

What my goal is to have my script run when the final container in launched
, right now I have this in the  git hub repo under s2i/bin/run/app.py

I get this error when I attempt to run this in openshift portal


/usr/bin/container-entrypoint: line 2: /tmp/scripts/run: Is a directory



/usr/bin/container-entrypoint: line 2: exec: /tmp/scripts/run: cannot
execute: Is a directory


I am thinking that the paths here are in the container right?

thanks again

Re: how to execute a script with S2i in openshift?

[Frederic Giloux]

Hi Brian

If you want your script to be executed by new builds it should be named
assemble. It can then call the original assemble script, that you may have
renamed, a python programm or any other thing you need. The run script is
called when the final container is launched not during the build.

Regards,

Frédéric

[logging]

[Himmat Singh]

Hi Team,

I have deployed rabbitmq, logstash server on openshift to make another ELK
pipeline for logging which supports some set of application and want to
forward logs from those application logs through ELK pipeline but
Elasticsearch will be the common For both EFK/ELK pipeline.

I have below secrets on openshift logging-elasticsearch :

logging-elasticsearch created 3 months ago

admin-ca
*
admin-cert
*
admin-key
*
admin.jks
*
key
*
searchguard.key
*
searchguard.truststore

I have grabbed truststore key using below command and used
truststore_password => tspass from elasticsaerch.yml :

sudo oc get secret logging-elasticsearch --template='{{index .data
"truststore"}}' | base64 -d > truststore.jks

Please help me with procedure i need to follow if i want to connect using
truststore keys,username,password for truststore.

Below is logstash.conf file : :

input {
  rabbitmq {

user => "admin"
password => "admin"
}
}
output {

truststore_password => tspass
index => "logstash-%{+.MM.dd}"
manage_template => false

   }
  stdout { codec => rubydebug }
}

I am facing below error:
