kandi X-RAY | pod Summary
Core API JSCoverage: 95.52%. Pod simplifies the workflow of setting up, updating and managing multiple Node.js apps on a Linux server. Perfect for hosting personal Node stuff on a VPS. There are essentially two parts: 1. git push deploy (by using git hooks) and 2. process management (by using pm2). It doesn't manage DNS routing for you (personally I'm doing that in Nginx) but you can use pod to run a node-http-proxy server on port 80 that routes incoming requests to other apps.

QUESTION
looking to understand the order in which kubenetes examine the pods using the 3 type of probes- startup, readiness and live.
How to understand or design these 3 probes correctly for normal applications? What is the chance of getting conflict or breaking the application if the startup probe has wrong entries
...ANSWER
Answered 2021-Jun-15 at 16:06This runs first. When it succeeds, the Readiness Probe and Liveness Probe are run continuously. If this fails, the container is killed.
Use this for "slow staring apps", you can use the same command as Liveness if you want.
The kubelet uses startup probes to know when a container application has started. If such a probe is configured, it disables liveness and readiness checks until it succeeds, making sure those probes don't interfere with the application startup. This can be used to adopt liveness checks on slow starting containers, avoiding them getting killed by the kubelet before they are up and running.
From configuring probes
Liveness probeThis is used to kill the container, in case of a deadlock in the application.
Readiness probeThis is used to check that the container can receive traffic.

You need to create a registry credentials secret for kubernetes, as it do not uses docker credentials.

I have an EKS node group with 2 nodes for compute workloads. I use a taint on these nodes and tolerations in the deployment. I have a deployment with 2 replicas I want these two pods to be spread on these two nodes like one pod on each node.
I tried using:
...ANSWER
Answered 2021-Jun-13 at 12:51You can use DeamonSet instead of Deployment. A DaemonSet ensures that all (or some) Nodes run a copy of a Pod. As nodes are added to the cluster, Pods are added to them. As nodes are removed from the cluster, those Pods are garbage collected. Deleting a DaemonSet will clean up the Pods it created.
See documentation for Deamonset
QUESTION
I couldn't find an equivalent k8s cli command to do something like this, nor any ssh keys stored as k8s secrets. It also appears to do this in a cloud-agnostic fashion.
Is it just using a k8s pod with special privileges or something?
Edit: oops, it's open-source. I'll investigate and update this question accordingly

QUESTION
I have two network policies (one with pod selector app=db and the other with app=proxy) and I have one pod to apply both network policies, the pod config doesn't allow to have 2 different labels with the same key app.
How can I do it in this case without modifying any network policies?
...ANSWER
Answered 2021-Jun-15 at 06:43If the pod/label/app selector is the only selector in each policy then it's not possible. The net policy probably needs a matchExpressions selector then a new label.
Ingress and Egress rules can supply an array of podSelectors for the network targets, or similar matchExpressions
QUESTION
On Mac OS X 10.7.5 on which perl-5.12.3 is installed, I needed to use the utf8::all module so I have manually installed utf8-all-0.024 (Note the minimum perl version of v5.10.0 on its CPAN page) The make test has failed but I've still installed it to see if it would work. It didn't work so I've decided to uninstall it. I've tried 2 methods given at perl.com the first method didn't work as it required perl-5.14.2 The second method gave this message:
ANSWER
Answered 2021-Jun-14 at 18:28You've made a mess of things by incorrectly installing the module. Specifically, you didn't install the dependencies.
Ideally, you should use the package manager that provided perl itself. But they don't provide every module. So you'd use the non-package manager approach:

QUESTION
We need to disable the automount of service account from our existing deployments in AKS cluster. There are 2 ways to do by adding the property "automountserviceaccount : false" in either in the service account manifest or pod template.
We are using separate service account specified in our application deployments, however when we looked in the namespace, there are default service account also created.
So inorder to secure our cluster, do we need to disable the automount property for both default and application specific service accounts?.
Since our app already live, will there be any impact by adding this to the service account s.
How to know the used service accounts of a pod and it's dependencies ?
...ANSWER
Answered 2021-Jun-14 at 16:55So inorder to secure our cluster, do we need to disable the automount property for both default and application specific service accounts?.
The design behind the default ServiceAccount is that it does not have any rights unless you give them some. So from a security point of view there is not much need to disable the mount unless you granted them access for some reason. Instead, whenever an application truly needs some access, go ahead and create a ServiceAccount for that particular application and grant it the permissions it needs via RBAC.
Since our app already live, will there be any impact by adding this to the service account s.
In case you truly want to disable the mount there won't be an impact on your application if it didn't use the ServiceAccount beforehand. What is going to happen though, is that a new Pod will be created and the existing one is being delete. However, if you properly configured readinessProbes and a rolling update strategy, then Kubernetes will ensure that there will be no downtime.
How to know the used service accounts of a pod and it's dependencies ?
You can check what ServiceAccount a Pod is mounting by executing kubectl get pods -o yaml. The output is going to show you the entirety of the Pod's manifest and the field spec.serviceAccountName contains information on which ServiceAccount the Pod is mounting.
QUESTION
I am using the ECK operator, to create an Elasticsearch instance.
The instance uses a StorageClass that has Retain (instead of Delete) as its reclaim policy.
Here are my PVCs before deleting the Elasticsearch instance
ANSWER
Answered 2021-Jun-14 at 15:38with the hope that due to the Retain policy, the new pods (i.e. their PVCs would bind to the existing PVs (and data wouldn't get lost)
It is explicitly written in the documentation that this is not what happens. the PVs are not available for another PVC after delete of a PVC.
the PersistentVolume still exists and the volume is considered "released". But it is not yet available for another claim because the previous claimant's data remains on the volume.
QUESTION
I am learning kubernetes and got into a point where I am very confused. I have installed metallb and ingress-nginx so it is possible to access content from outside. I saw several examples that are using nginx image running in pod despite they are also using ingress-nginx.
Isn't ingress-nginx capable to do all work as nginx image? Otherwise what roles those two play?
I need to deploy express server where I would like to utilize some nginx features like gzip so it is where reverse proxy comes.
So do I need to make it work on ingress-nginx level or from nginx image? And if I need nginx image does it mean that I need to run separately nginx image and my built node image with my express app?
...ANSWER
Answered 2021-Jun-14 at 12:34Short answer: No
But it's complicated.
nginx image you mentioned is one of the most popular images (5th on the Docker Hub, by the time of this writing), is relatively small (133MB), and is easy to remember. That's why it is widely used as an example in many tutorials.
Isn't ingress-nginx capable to do all work as nginx image?
To some extent.
Pod and Ingress are different Kubernetes resources, and they act differently. nginx image is usually deployed as a container inside a pod.
In case of nginx ingress controller, similiar image is used for both Pod and Ingress (mentioned below).
Whenever you deploy (for example) a rewrite rule in ingress controller
