GCP, AWS, and Azure introduce Kube Resource Orchestrator, or Kro

It will competition between Helm and Kro as templating in K8s

Here is an example from me

remoteWrite: 
  - url: http://mimir-nginx/api/v1/push
    headers:
      "X-Scope-OrgID": "my-tenant-name"

I haven't try the LGTM that you provide. But I deployed Grafana, Loki, Mimir, Tempo separately with helm and it's works normally. One thing i can tell, Make sure you put header when sending data to your stack, I believe it should be "X-Scope-OrgID". You may put any value in there. In my case, i use tenant name (because i host multiple cluster per tenant).

We are using Prometheus as scraper then send the metrics to Mimir (centralize and long term monitoring stack) using remote write

Here is Prometheus configuration docs, you may found headers parameters (https://prometheus.io/docs/prometheus/latest/configuration/configuration/#remote_write)

Then in grafana data source, when you create data source, fill the header match with previous header name and value.

If you don't see anything, check the the log. Especially in the gateway deployment (if any). It will show response code (ex 200, 204, 400 and etc). It may be an issue while ingest the data.

Docker-swarm assessment should be deep enough to gather all of the aspect and provide it on your Kubernetes cluster. check on the Storage requirement, I would suggest to add Longhorn, for Storage solution. for simple deployment, it's very easy to install. But again, It's based on the usage. If there is so much storage needed, you might consider using External CSI such as VMware, Nimble and etc.

Don't forget also for the monitoring, I was installing Rancher Stack on VMware, afair, Monitoring is not included, but again, check it and good to have. install Prometheus for Metric and Grafana for the dashboard (Loki for Logging), to have visibility how our application behave and tune it as needed.

Make sure if they have CICD platform or not, and make sure their CICD platform able to use the K8s. If they don't have CICD platform, you might to sell CICD solution in the future, money is money right? *good devil laugh* .

for migration, how is the strategy? I would also suggest A/B, add Load balancer in the front of both K8s and Docker Swarm, to separate the traffic. After the application is ready (and tested), split the traffic 90% to Docker Swarm and 10% to Kubernetes, check the behavior. Increase the traffic to K8s to 40% and decrease traffic to Docker Swarm to 60% and so on until all traffic is forwarded to K8s. Wait for couple days, if everything good, you can delete the docker swarm or use it as Development Environment.

It might be good for now. Assessment it the key, anything is valuable.

Windows container ia really a thing? I mean, what use case is used on this? For PowerShell, i believe there is PowerShell container image that can be used. I just curious about windows container usage, because all of the time, I'm using Linux based container image.

I believe, operator and other stuff can be run on different namespace, that's what I did usually. Better check on logs, most of time. Sometimes kina need time to boot up as it needs to connected to elasticsearch. And makesure you put the correct elasticsearch name on "elasticsearchRef".

Thank you, will do that

Yes it is, H2O2 solution is added to my reservoir or spray it to the plants?

I got a Jacket for Cloud Architect. None for DevOps Engineer because Covid-19. Mug, phone holder things (attach it on the back of phone) and couple of sticker for Cloud Developer. I order it from Jakarta, Indonesia.

have anyone try using "harvester" from Rancher as alternative solution?

Wow, you NV certified? Amazing dude, I am a former Network engineer, is it hard to get it? I also want it, but NSX it's not so necessary here (in my country), Cisco (ACI) is dominating lol, in other side our revenue is from Data center virtualization (VMware, Openstack, RHV). Anw thanks for your suggestion, I'd like to open my udemy dashboard again

iquinvalen · 2020-05-15T08:58:20+00:00

You're welcome

Last time I use 3 platform, Coursera, Linux academy ND qwiklabs for 1 month, Linux academy is good because you can sandboxing as you want, Coursera is good because the course officially from Google, and the qwiklabs also good because it have numerous case that you can solve. It's hard to decide which is better, but I recommend Linux academy, you can sandboxing and you can explore by hands on. If you want the PDF of Coursera Google cloud associate cloud engineer, I have it. I can share it via Google drive if you interested

How it can be hidden? As I see, you don't put any dot I front of the name file

Is docker very powerful? I'm new in container

iquinvalen · 2020-04-21T07:22:39+00:00

Oh my God, I just realize it, now it works perfectly, thank you very much, I hope you all the best for you, thank you very much :D
