draft connect timeout issue #776

Closed quantum-fusion closed 6 years ago

quantum-fusion commented 6 years ago

The problem is that the draft connect does not get the buildlID, and it times out.

The docker hub location is here: https://hub.docker.com/r/joethecoder2/example-python/tags/

I followed the instructions for the draft python example here: https://github.com/Azure/draft/blob/master/docs/getting-started.md

Yes, this transcript is showing a failure with a timed out on draft connect, and this is still open.

See #437 comments as well.

The main reasons draft connect times out:

You said you are trying the example-python project?

Yes, this is the example-python project example that was executed.

Could you execute a kubectl get pods in the default namespace? Thanks!

Helm shows this is in a Deployed state. Can you tell me the command to change to a READY state?

It looks like it is stuck in a Pending status.

radu-matei commented 6 years ago

See, your example-python-python-2616207425-f2hvq pod is in pending state.

Could you execute a kubectl describe pod example-python-python-2616207425-f2hvq?

(If it's minikube, and you have some services already running, I suspect a lack of resources on your machine)

Yeah, as I expected: FailedScheduling No nodes are available that match all of the following predicates:: Insufficient memory (1).

Try removing some of the deployments (if that's an option) and try again.

radu-matei commented 6 years ago

Please note that if your pods were part of a deployment object, then just deleting the pods will result in the scheduler trying to meet the desired state of the respective deployment, meaning you will get the pods back - what you want to do is delete the deployment itself - more info here https://kubernetes.io/docs/concepts/workloads/controllers/deployment/

success. Thank you.

radu-matei commented 6 years ago

Glad to hear! Will close this issue, but feel free to re-open it if you have any more questions.

quantum-fusion commented 6 years ago

I had one side question, about helm, and wanted to know, can I pass command line arguments, like I pass JAVA arguments from the command line?

quantum-fusion commented 6 years ago

Thanks again, for helping with this issue, resolution.

radu-matei commented 6 years ago

If you're talking about passing command line arguments to the application you're starting in your container, you can either add them directly in your Dockerfile, as your entrypoint, or you can pass them in your Helm template for your deployment - more info here https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/

quantum-fusion commented 6 years ago

I have an entire SpringBoot service, that will deploy in a POD, however the problem is that I can not get the arguments to pass through to the application.

Google claims that their PODS are immutable, and can not be configured.

quantum-fusion commented 6 years ago

Two questions about DRAFT:

The base project is here: https://github.com/quantum-fusion/springboot_swagger_example-master-cassandra

Can we download this project using GIT and then do these two things? If so, is there command line example for 1.) and 2.) ?

1.) Does draft compile the service to make a chart using draft create and draft up, will it automatically build the service using singlePod.yaml? If so, how?

2.) I am trying to figure out what the helm command is, to install this package, and also to set the values for cassandra_ip, cassandra_port, login, and password , is this possible from command line?

Looking at the results from draft create, and then followed by draft up.

See errors, that I labeled 1 , 2, 3, and 4. These errors are suspect.: 1.) Status: Downloaded newer image for python:onbuild

2.) # Executing 3 build triggers 2018/05/23 14:42:15 error while building: COPY failed: stat /var/lib/docker/tmp/docker-builder681976653/requirements.txt: no such file or directory

Outstanding questions/problems/known issues/limitations:

1.) The problem is that the Dockerfile automatically generated doesn't know about the service, and I have one that is part of the project.
https://github.com/quantum-fusion/springboot_swagger_example-master-cassandra/blob/master/dockerbuild/Dockerfile

The problem, is that DRAFT appears to expect that the JAR file already be compiled by maven as a pre-dependency. Is this true?

Does draft compile the service to make a chart using draft create and draft up, will it automatically build the service using singlePod.yaml? If so, how?

2.) Problem is that Google states that configurability for Pods doesn't work, because Pod arguments are immutable, and templating is not allowed: I am trying to figure out what the helm command is, to install this package, and also to set the values for cassandra_ip, cassandra_port, login, and password , is this possible from command line?

This is as far as I got, for a complex case springboot project example.

I will try to remedy as follows:

quantum-fusion commented 6 years ago

An error fell out, that is a draft bug: The error is that draft create thought this was a python project, which is a bug.

FROM python:onbuild ENV PORT 8080 EXPOSE 8080 ENTRYPOINT ["python"] CMD ["app.py"]

quantum-fusion commented 6 years ago

The actual Dockerfile should be as follows: FROM java:8 MAINTAINER info@technologyventureslimited.com EXPOSE 8080 9042 ADD ./spring-boot-web-0.0.1-SNAPSHOT.jar . ENTRYPOINT ["java", "-jar", "spring-boot-web-0.0.1-SNAPSHOT.jar"] CMD java -jar spring-boot-web-0.0.1-SNAPSHOT.jar $@

quantum-fusion commented 6 years ago

draft up expects that the spring-boot-web-0.0.1-SNAPSHOT.jar exist in the project, and therefore a mvn clean install has to be executed in order to create the JAR dependency.

These are the steps that I am using to test DRAFT.

  1. %git clone https://github.com/quantum-fusion/springboot_swagger_example-master-cassandra

  2. %mvn clean install -DskipTests

  3. %draft create

  4. %draft up

Question: I added a symbolic link for the Dockerfile.lrwxr-xr-x 1 me staff 24 May 23 15:36 Dockerfile -> ./dockerbuild/Dockerfile

Errata question: Is there something wrong with DRAFT that doesn't either see the symbolic link, or some other reason that DRAFT isn't seeing the Dockerfile when I use the draft up command?
