Docker, global variables, app.yaml

John Moser — Tue, 12 Nov 2019 03:57:38 -0500

Dear Ivy Team

It looks like there are 3 places where the global vars can be set : - inside IAR - in DB - in app.yaml

So what is the order how Ivy is looking for the global vars ?

Thanks & Regards, John Moser

Docker, applications folder, deployment

John Moser — Fri, 08 Nov 2019 02:34:12 -0500

Dear Ivy team

When we are building the KLARA image in windows, we get an issue with long file names. We have decided to keep the deployed IARs inside the image. Therefore the deployed apps are part of it. The folder structure looks like this :

jam:~/.../applications/luz$ ls -ltr
total 80
drwxr-xr-x 3 jam jam 4096 Mai  1  2019 luz_components
drwxr-xr-x 3 jam jam 4096 Mai  1  2019 luz_docs_process
drwxr-xr-x 3 jam jam 4096 Mai  1  2019 luz_finance
drwxr-xr-x 3 jam jam 4096 Mai  1  2019 luz_xhrm_processes

and each folder contains all the Ivy stuff. So no wonder build under Windows is an issue due to long file names.

Question : What is needed in these folders ? can we skip some folders/files ?

Request for 7.3.2 : Can you provide a "applications"-less Ivy version which does not require 7.4 ?

Docker, set permissions by yaml file

Hi Ivy Team

Is it possible to configure the permissions also by a yaml file ?

Docker, pass Ivy license as env prop

John Moser — Thu, 19 Sep 2019 04:51:42 -0400

Dear Ivy team

Is it possible to pass the Ivy license via env prop ?

Reason for my question : as you might know we in KLARA want to build our own image. If the license has to be provided as a file in a certain directory then our image, which is hosted somewhere in the cloud, contains the license. May be not so nice from your point of view.

The idea is that we store the license as a secret and inject it at startup of the image.

Docker, Migration 7.2.1 to 7.3.1

John Moser — Thu, 29 Aug 2019 10:33:45 -0400

Hi Ivy Team

I am getting following error message during Ivy startup after I migrated to the 7.3.1 image :

java.lang.Exception: The system database (jdbc:postgresql://10.172.0.9:5432/ivysystemdb_7) with all tables already exists (Version: 50). But was created with a older version of the ivy Engine. at ch.ivyteam.ivy.server.configuration.command.CreateDbCommand.checkIfCreationNeeded(CreateDbCommand.java:114) at ch.ivyteam.ivy.server.configuration.command.CreateDbCommand.createSystemDatabase(CreateDbCommand.java:63) at ...

What has to be done to fix this problem.

Thanks & Regards John

Docker, set admin client / system db values via yaml file

John Moser — Tue, 16 Jul 2019 11:34:51 -0400

Dear Ivy Team

In the Non-Docker world, we have a deployment IAR, which writes config values fed via a script.

With Docker we want to avoid that. The global variables we already configure them via app.yaml. What would be (in the future ?) the best way to configure permissions, iwa_applicationproperty, etc

Docker, Rerun image with IAR installation

John Moser — Mon, 15 Jul 2019 12:20:24 -0400

Dear Ivy Team

In your example setup, the ivysystemdb exists as an image and is therefore created from scratch every time docker-compose is run. That means you can run the same image as many times as you want.

If we do that in our Dev environment, we are running into the versioning problem (I think), which prevents to rerun of the same image multiple times (Error : The process model version '1' of process model 'luz_web' of application 'luz' is currently unavailable because of maintenance.)

Since our image does the installation as well, it can't be "used" more then one time, which means for each restart we would need a new build of a new version of our app.

Or do I miss something ?

Best regards John

Docker, dropins, AuthenticationValve

John Moser — Fri, 31 May 2019 10:29:36 -0400

Hi Ivy Team

I am building a Docker image based on axonivy/axonivy-engine:7.2.1. In our project we have a few JARs which should go into the dropins folder but during Ivy startup I get the following error :

14:13:05.368 ERROR [org.apache.tomcat.util.digester.Digester] [localhost-startStop-1]    Begin event threw exception
    java.lang.ClassNotFoundException: com.axonivy.auth.valve.AuthenticationValve cannot be found by ch.ivyteam.tomcat_8.5.34.201810151000 ...

4:13:05.380 ERROR [...apache.catalina.startup.ContextConfig] [localhost-startStop-1]    Parse error in context.xml for [/ivy]
org.xml.sax.SAXParseException; systemId: file:/usr/lib/axonivy-engine-7x/webapps/ivy/META-INF/context.xml; lineNumber: 13; columnNumber: 66; Error at (13, 66) : com.axonivy.auth.valve.AuthenticationValve cannot be found by ch.ivyteam.tomcat_8.5.34.201810151000

So far I did the following:

1) Dockerfile:

COPY --chown=ivy:ivy axonivy7-engine-folder-setup/dropins/* /usr/lib/axonivy-engine-7x/dropins/

2) Check if files exist after Ivy startup:

ivy@22ae6389e9e5:/usr/lib/axonivy-engine-7x/dropins$ ls -ltr
total 956
-rwxr-xr-x 1 ivy ivy   2028 Mar  8  2018 README.html
-rwxr-xr-x 1 ivy ivy 962431 Jul 19  2018 com.axonivy.auth.valve.AuthenticationValve_1.0.0.201807190929.jar
-rwxr-xr-x 1 ivy ivy   1622 Aug  1  2018 workflow.klara_patchNoBusinessCaseQuery_1.0.0.201807311434.jar
-rw-r--r-- 1 ivy ivy   8078 Nov  5  2018 webserver.rest.extension.patch_1.0.0.201805241153.jar

3) Check if JARs are listed using ss in console, but all the JARs in dropins are not listed:

Axon.ivy Engine is running and ready to serve. [19778ms] Type 'shutdown' and confirm with ENTER to stop the running engine instance ss "Framework is launched."

id  State       Bundle
0   ACTIVE      org.eclipse.osgi_3.13.0.v20180409-1500
                Fragments=2, 1
1   RESOLVED    ch.ivyteam.ivy.osgi.classpatcher_7.2.1.201811131504

                Master=0
3   ACTIVE      org.eclipse.equinox.simpleconfigurator_1.3.0.v20180502-1828

As far as I understood, one should copy the JARs into the dropins folder and it should work

Thanks & Regards John

Docker, Global Properties, Placeholder, app.yaml

John Moser — Mon, 20 May 2019 11:20:27 -0400

Hi Ivy Team

Assuming I have a global prop such as :

myGlobalProp: http://myIP:1234/whatever

myIP is different for Dev, Test and Prod. Is there a way to "inject" myIP at startup of the Docker image ?

Or generally:

If I want to build an image which should be deployed in Dev, Test and Prod, is there a way to parameterize all the config files used for the Ivy Engine (yaml, xml, etc.) ?

Thanks & Regards John

Docker, prevent container being stopped after an exception

John Moser — Wed, 15 May 2019 11:54:13 -0400

Hi Ivy team

Is there a switch or something to keep the container running even if there was a (fatal) exception at boot time of Ivy ?

Currently it's slightly painful to debug ...

Thanks & Regards John Moser

Docker, Dockerfile, what USER to apply

John Moser — Wed, 15 May 2019 11:25:17 -0400

Hi Ivy team

We want to build our own image and we are running in some troubles regarding the USER :

FROM axonivy/axonivy-engine:7.2.1

USER root or ivy or ... ? <--- which one to apply ?

COPY ... CMD ... etc.

Thanks & Regards John Moser

PS: can someone with enough "reputation" put dockerfile into the tag list ?

Docker, IAR deployment

John Moser — Wed, 15 May 2019 11:10:37 -0400

Hi Ivy team

I have a zip file with IARs (but w/o app.yaml) and I use COPY to copy the zip file to the deploy folder of the Ivy engine, where it should be deployed at startup - according to the doc.

a) is this procedure correct ? b) If yes then I get -> Caused by: java.nio.file.FileSystemNotFoundException: /usr/lib/axonivy-engine-7x/applications/projects/authentication_tool_ivy/1.zip

There is indeed a authentication_tool_ivy-7.2.0-SNAPSHOT.iar in the zip file.

Any idea why this error happens ? Any more specific description how the files have to be named ? Is the order how the IARs are listed in the zip file relevant ?

Thanks & Regards John Moser
