regarding Deployment of helm charts

Sahilgandas1 opened this issue 3 years ago · comments

The helm charts you guys have mentioned are not getting deployed there may be some issues with charts i guess. You should clearly mention what all are dependencies for ecah Fiware GE's so that according to that we can make changes into Yaml file. But as of now no mention and how we can test weather our deployed charts are ready to use or not ?

Hi, can you tell which charts you are not able to install and what exact errors you are seeing? We tested all of them.
The charts itself are ready as soon as the deployments are ready, we do not offer a "helm test" currently.

I am trying to install Orion and Iotagent both .

For orion V2 i have changed image name in values.yml but pod is going into crashbackloopoff state. when i checked Container logs it is not showing nothing. But Docker ps -a showing the following for container.
ba5d7eef0343 ed9b9cf75e26 "/usr/bin/contextBro…" About a minute ago Exited (1) 10 seconds ago k8s_orion_orion-5f8c59dc5b-knjpx_default_30136b91-e7e4-439f-8670-52408b3cbf6c_211
May be it is not able to deploy MongoDB.
Does this chart automatically deploy mongo or we have to externally deploy and then make the connection.
If it deployes automaticlly then can you please mention where i have to do changes in Values.yml.
For OrionLD container again and again going in exit state . As shown below-

Docker logs showing :

terminate called after throwing an instance of 'mongo::UserException'
what(): Empty host component parsing HostAndPort from ""

While installing IotAgent it is giving some error below :
on helm install iotagent -

Error: Ingress.extensions "iotagent-iotagent-ul-south" is invalid: spec: Invalid value: []networking.IngressRule(nil): either backend or rules must be specified

But when i do helm ls :

**NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION

But its pod is running and container is also running.

Thanks for the additional information.

Orion(both versions) do require a mongo-db, the chart does not install it. You can find a configuration for mongo in our load-tests: https://github.com/FIWARE/load-tests/tree/master/testReports/orion-ld/tiny#installation
If you run into additional problems, you can increase the log-level. Its set to warn by default, but you can change it via the values.yaml.

I will look into the IoT-Agent issue next week.

Sahilgandas1 · Answer 4 · Fri Jul 09 2021 20:25:04 GMT+0800 (China Standard Time)

Ok thanks i will try installing mongo-db before and then install orion and will see weather it will work or not.
if any issue will arise i will paste here in loop.

The bitnami mongodb chart runs with authorization enabled by default(see https://github.com/bitnami/charts/tree/master/bitnami/mongodb#mongodb-parameters). In order to connect, orion requires the authorization information to be set. See: https://github.com/FIWARE/helm-charts/blob/main/charts/orion/values.yaml#L254-L260

hi @wistefan
Is there any sepcific document where a layman user can understand what all configurations change a user have to do in this chart so that it get connects with mongodb and can work properly. please provide what all configuration a user have to do or some demo /document where we can understand. It is getting too complex to understand.

Stefan Wiedemann · Answer 8 · Mon Jul 12 2021 20:11:28 GMT+0800 (China Standard Time)

Hi,
every configuration is documented inside values.yaml: https://github.com/FIWARE/helm-charts/blob/main/charts/orion/values.yaml
Beside that, there is the already mentioned load-test repository that offers a working configuration.
I'm sorry, but the target of those charts is to provide production-grade deployment scripts. To use something production grade, at least base-knowledge on kubernetes and helm is required.

I have tried after doing authentication but still i m getting below error:

Stefan Wiedemann · Answer 10 · Tue Jul 13 2021 14:27:04 GMT+0800 (China Standard Time)

Can you please provide the values.yaml that you are using for mongo and the one for orion?

Sahilgandas1 · Answer 11 · Tue Jul 13 2021 15:36:10 GMT+0800 (China Standard Time)
