Deploy geode on kubernetes
Hi all,
Anyone has idea how to deploy geode on kubernetes correctly?
kuberetes requires process to run in fore-ground mode, but gfsh start
processes in background-mode
I found this guy (https://github.com/markito/geode-kubernetes)
he's doing tricky thing by running infinite while loop after starting gfsh
while true; do
sleep 20
done This works, but in case of failure the pod will never be restarted.
So failure recovery doesn't really work.
I'm thinking couple of other solutions:
1/ Start using java command (not via gfsh), this will start process in
fore-ground mode
2/ Using gfsh, but instead of infinite while loop, having a script to
monitor status of geode members and exit in case of failure
Anyone has better idea on this?

Thanks
Kien

You can also tail the logs
<https://github.com/sbawaska/charts/blob/fe573cd28ce0b9feb832b1c2d5154922ee4f6903/incubator/geode/templates/server.yaml#L34>
after starting the server. This also allows you to see the logs with the
"kubectl log" command:
I am also working on a helm chart for geode. Would appreciate any feedback:

The jira below was created to add foreground options to gfsh and fix that.
On the ticket there is also a comment with a good bash example using the Launcher class.

Re: Deploy geode on kubernetes
Posted by Akihiro Kitada <ak...@pivotal.io>.
Hello Kein,
Why don't you call waitOnLocator() after calling start() as below
-----
locatorLauncher.start();
System.out.println("Locator successfully started");
locatorLauncher.waitOnLocator();
System.out.println("Locator is shut down");
-----
In this case, the main thread waits someone to stop at the line calling
waitOnLocator().
If you stop the locator (for example, with using gfsh stop locator
command), then you will see "Locator is shut down" as a result.
Thanks, regards.

Hi Akihiro,
Hmm, I'm trying following example from
https://geode.apache.org/docs/guide/10/configuring/running/running_the_locator.html
import org.apache.geode.distributed.LocatorLauncher;
public class MyEmbeddedLocator {
public static void main(String[] args){
LocatorLauncher locatorLauncher = new LocatorLauncher.Builder()
.setMemberName("locator1")
.setPort(13489)
.build();
locatorLauncher.start();
System.out.println("Locator successfully started");
}
}
This script start locator in background, print the message "Locator
successfully started" and exited,
am i using it correctly?

Hello Kein,
As Bruce mentioned, you can launch locators and cache servers processes in
the foreground with using LocatorLauncher and ServerLauncher classes in
your java programs.

thanks Akihiro,
I like the #1 better, but using LocatorLauncher or ServerLauncher it also
create background process right?
I was running ps grep command to get full java process start by gfsh, but
it’s urgly solution.

Hello Kein,
I prefer the solution 1.
>1/ Start using java command (not via gfsh), this will start process in
fore-ground mode
If using LocatorLauncher and ServerLauncher classes, you can write Locators
and Cache Servers launcher in fore-ground mode with less coding.
Thanks.

Use the LocatorLauncher and ServerLauncher classes to launch processes
in the foreground.
