I have deployed the ova with the factorial app. Now how do I test it?

[atul.nirmalkar1]

Hi everyone,

Hey guys, I am having some problems on how to run the factorial application. I have installed the sdk, and I have also built the factorial app as described in the cookbook.

After building the app, I run this command (I source iox_sdk_env before running the following command)

imgb.sh -c repack-rootfs -f ~/Projects/cisco/cisco_iox_sdk-x86_64-v0.1/images/e500v2_linux_guest/archives/e500v2-linux-guest.rootfs -o /tmp/myiox-app/e500v2-linux-guest.rootfs -s ./imgb_cb_script.sh

and I get the following output:

/home/user/Projects/cisco/cisco_iox_sdk-x86_64-v0.1/tools/scripts/imgb.sh: line 216: return: -1: invalid option

return: usage: return [n]

/home/user/Projects/cisco/cisco_iox_sdk-x86_64-v0.1/tools/scripts/imgb.sh: line 216: return: -1: invalid option

I have attached the imgb_cb_script.sh.

Now I generate the OVA file with the new rootfs, by issuing the following command:

packing.sh -a 0 -s ~/Projects/cisco/cisco_iox_sdk-x86_64-v0.1/tools/verifier/ /tmp/myiox-app/

And here's the output:

This output tells me that the ova file test.ova is now created. And indeed it is created. I then deploy the ova on the router, and after deploying the app, I start the application from the cisco router web portal. But there is not output to check. I then use minicom to log into the router, and I check to see if there is any log file in /data/ directory. There isn't any.

(The factorial code created a log file in /data/ directory "fptr=fopen("/data/app.log", "w");")

How can I make sure that my application has been repacked correctly in the new rootfs, and the test.ova is created properly. How can I verify that the app is running?

Any help is greatly appreciated. Thanks.

I have also attached imgb.sh script, the makefile used to generate the factorial binary using the toolchain, and the code of factorial.

HI Atul,

I understand you created the ova application successfully, and deployed it the application on C819 through Local App Manager. But you need to access the Guess OS (run "virtual-service connect name yourappname console" to access the Guess OS) to check the log after that, not in the IOS. Please refer to the chapter 4.10 of 819-IOx-SDK-Cookbook.docx for details.

Thanks,

Steve

Hi thanks a lot for replying,

I did manage to run the app from the OVA, by logging into the console of the router and running it as command. I figured out that the imgb_cb_script copied the factorial.bin to /usr/bin of the rootfs.

Thanks again.

Hi Atul,

As you mentioned, the ova application is created, deployed, and started successfully. It means the guest OS is started.

But not sure if you run the factorial code yet. You should run the bin file manually: /usr/bin/factorial.bin. Please try it.

Meanwhile, you may use any example bin file which is compiled by the C819 IOx SDK toolchain, put it in the guest OS (wget is supportable), make it executable, and run it for further testing. If you really did not run it successfully, you may add some print information for debug.

Thanks,

Steve

Hi Steve,

I've got a Cisco 4G LTE M2M since a few days.

I'm trying to get started with the SDK (also following the Cookbook 819 procedure with the factorial example).

I guess that all the process to generate the OVA is correct...

Here is my result:

After that, I deployed 'test.ova' on the router via the Cisco Application Manager (status is RUNNING).

Connecting to the VM's interface also succeed with the command:

virtual-service connect name devapp console

After that, when I'm in the Linux context,

How can I test or launch my factorial application (I can't see the '/data/app.log' file written with the app, so my conclusion is that the program never started)?

Moreover, in the Cisco Application Manager, Manage>Show logs for the deployed and running application, I can't see any log.

I also read your post, but I'm unable to find the binary in the Linux context in order to start the program.

After deployment via the web interface, what's the procedure to start the factorial program and see the result?

Thanks in advance.

Best regards,

Adrien van den Haak

Hi all,

In my previous post, I was not able to find the binary 'factorial.bin' (following the factorial example from the cookbook) in /usr/bin (on the linux context of the Cisco 819 router).

Actually, the issue is now resolved.

The problem was during the copy of the binary in the rootfs '/usr/bin' target directory during the rootfs re-packaging.

The script 'imgb_cb_script.sh' wasn't correctly executed (fakeroot test and copy of the binary in the rootfs /usr/bin directory).

I forgot to call the main function with the args in this script (main $*).

PROBLEM SOLVED. Hope it will help someone.

Thanks.

Cheers,

Adrien
