QUESTION
I'm deploying a spring-boot application and prometheus container through docker, and have exposed the spring-boot /actuator/prometheus endpoint successfully. However, when I enable prometheus debug logs, I can see it fails to scrape the metrics:
ANSWER
Answered 2022-Feb-07 at 22:37Ok, I think I found my problem. I made two changes:
First, I moved the contents of the web.config.file into the prometheus.yml file under the 'spring-actuator'. Then I changed the target to use the hostname for my backend container, rather than 127.0.0.1.
The end result was a single prometheus.yml file:
QUESTION
I've been trying to get over this but I'm out of ideas for now hence I'm posting the question here.
I'm experimenting with the Oracle Cloud Infrastructure (OCI) and I wanted to create a Kubernetes cluster which exposes some service.
The goal is:
- A running managed Kubernetes cluster (OKE)
- 2 nodes at least
- 1 service that's accessible for external parties
The infra looks the following:
- A VCN for the whole thing
- A private subnet on 10.0.1.0/24
- A public subnet on 10.0.0.0/24
- NAT gateway for the private subnet
- Internet gateway for the public subnet
- Service gateway
- The corresponding security lists for both subnets which I won't share right now unless somebody asks for it
- A containerengine K8S (OKE) cluster in the VCN with public Kubernetes API enabled
- A node pool for the K8S cluster with 2 availability domains and with 2 instances right now. The instances are ARM machines with 1 OCPU and 6GB RAM running Oracle-Linux-7.9-aarch64-2021.12.08-0 images.
- A namespace in the K8S cluster (call it staging for now)
- A deployment which refers to a custom NextJS application serving traffic on port 3000
And now it's the point where I want to expose the service running on port 3000.
I have 2 obvious choices:
- Create a LoadBalancer service in K8S which will spawn a classic Load Balancer in OCI, set up it's listener and set up the backendset referring to the 2 nodes in the cluster, plus it adjusts the subnet security lists to make sure traffic can flow
- Create a Network Load Balancer in OCI and create a NodePort on K8S and manually configure the NLB to the ~same settings as the classic Load Balancer
The first one works perfectly fine but I want to use this cluster with minimal costs so I decided to experiment with option 2, the NLB since it's way cheaper (zero cost).
Long story short, everything works and I can access the NextJS app on the IP of the NLB most of the time but sometimes I couldn't. I decided to look it up what's going on and turned out the NodePort that I exposed in the cluster isn't working how I'd imagine.
The service behind the NodePort is only accessible on the Node that's running the pod in K8S. Assume NodeA is running the service and NodeB is just there chilling. If I try to hit the service on NodeA, everything is fine. But when I try to do the same on NodeB, I don't get a response at all.
That's my problem and I couldn't figure out what could be the issue.
What I've tried so far:
- Switching from ARM machines to AMD ones - no change
- Created a bastion host in the public subnet to test which nodes are responding to requests. Turned out only the node responds that's running the pod.
- Created a regular LoadBalancer in K8S with the same config as the NodePort (in this case OCI will create a classic Load Balancer), that works perfectly
- Tried upgrading to Oracle 8.4 images for the K8S nodes, didn't fix it
- Ran the Node Doctor on the nodes, everything is fine
- Checked the logs of kube-proxy, kube-flannel, core-dns, no error
- Since the cluster consists of 2 nodes, I gave it a try and added one more node and the service was not accessible on the new node either
- Recreated the cluster from scratch
Edit: Some update. I've tried to use a DaemonSet instead of a regular Deployment for the pod to ensure that as a temporary solution, all nodes are running at least one instance of the pod and surprise. The node that was previously not responding to requests on that specific port, it still does not, even though a pod is running on it.
Edit2: Originally I was running the latest K8S version for the cluster (v1.21.5) and I tried downgrading to v1.20.11 and unfortunately the issue is still present.
Edit3: Checked if the NodePort is open on the node that's not responding and it is, at least kube-proxy is listening on it.
...ANSWER
Answered 2022-Jan-31 at 12:06Might not be the ideal fix, but can you try changing the externalTrafficPolicy to Local. This would prevent the health check on the nodes which don't run the application to fail. This way the traffic will only be forwarded to the node where the application is . Setting externalTrafficPolicy to local is also a requirement to preserve source IP of the connection. Also, can you share the health check config for both NLB and LB that you are using. When you change the externalTrafficPolicy, note that the health check for LB would change and the same needs to be applied to NLB.
Edit: Also note that you need a security list/ network security group added to your node subnet/nodepool, which allows traffic on all protocols from the worker node subnet.

I set up my development environment on Fedora 35 and when I run any brownie command such as $ brownie console or even brownie --version I get the following error:
ANSWER
Answered 2021-Dec-22 at 20:40The problem here seems to be Python 3.10.1!
I used anaconda to create a new virtual environment with Python 3.8.12, installed brownie using pipx install --python python3.8 eth-brownie and it worked!
The trick here was, to also tell pipx to use another python version, otherwise it would create a dependency to the global python version, which is python 3.10 in my case.
QUESTION
I am making a low level library that requires initialization to work properly which I implemented with a init function. I am wondering if there is a way to make the init call be called once the user calls a library function ideally without:
- Any overhead
- No repeated calls
- No exposed global variables. (my current solution does this, which I don't quite like)
my current solution as per comment request:
...ANSWER
Answered 2021-Dec-13 at 06:56If you're happy with a solution that is a common extension rather than part of the C standard, you can mark your init function with the constructor attribute, which ensures it will be called automatically during program initialization (or during shared library load if you eventually end up using that).

I'm getting an error when attempting to compile Haskell tests using test-framework on Windows.
Steps to reproduceCreate a new library using Stack:
...ANSWER
Answered 2021-Nov-20 at 14:21I assume, given when you posted this question, you are using LTS 18.17. Looking at that LTS, it uses mintty 0.1.3. Looking in mintty 0.1.3's cabal file shows a special flag that is enabled by default that means that System.Console.MinTTY.Win32 is not included. The comments in that cabal file say that that flag should be used when using Win32 2.13.1.0 or newer.
However, when I look at LTS 18's configuration in Stackage, I can see that it is using Win32 2.6.2.1, so that flag ought to be set to false for this package to work.
So let's check that in the Stackage build constraints. I see that another flag is being set, and it seems to be an old flag that is no longer used (looks like it was used in an older 0.1.2 version). This must be the problem.
The solution: manually set the flag in your stack.yaml:
QUESTION
We have a Prometheus container and various other services and metrics exporter containers running in a custom docker network.
In our local dev environment on Win 10 x64 using Docker desktop everything works fine, the Prometheus container can scrape the metrics exporter containers in the custom network as well as the exposed Docker metrics from the host (Win 10).
On our Ubuntu 18.04 Linux host, latest Prometheus 2.30.3 container scrapes the metrics exporter containers in the custom network just fine but is unable to scrape the exposed Docker metrics from the host.
These are the specs and config for the Ubuntu host:

in our case UFW on Ubuntu was blocking the requests on docker0 interface from our containers that are in a custom docker network.
You can see this by checking the UFW logs, you will see how it blocks the requests for 172.17.0.1 (--> host.docker.internal) on the specified metrics port.
Disabling UFW temporarily made it work, Prometheus could now scrape the Docker metrics on the host.
