There is an annoying bug in Kubernetes 1.6 running on GCE with Calico/Flannel networking operating via CNI plugin interface.
You may experience same issue if kubelet on your nodes runs with options
--network-plugin=cni --cloud-provider=gce
When a new node is added to the k8s cluster it’s recognized as ‘Ready’ but no pods except Calico/Flannel pod are being scheduled there.
This is quite common nowadays to have some TLS terminatin reverse proxy in front of your REST API. Nginx is being used frequently for this purpose.
The problem I faced and spent some time trying to resolve is that API backing Nginx responds in JSON, but if something is wrong with the request itself or Nginx can’t reach the backend Nginx returns error page in ‘text/html’.
Have Ubuntu 14.04 installed on the VM I use as a programming/testing environment.
Golang packages in Ubuntu 14.04 repo are a bit old:
Be aware Google Cloud storage sets Cache-Control:public, max-age=3600
header for all files by default. This means files are going to be cached
by browsers and proxies so it is going to take up to an hour for folks on the Internet
to see an update.
I’ve decided to decrease default max-age value to 600. So I upload blog files
with -h option set now:
gsutil -h "Cache-Control:public, max-age=600" rsync -d -r . gs://<bucket_name>/
What time is it? Migration time! Long story short I’ve decided to play a bit with Google Cloud services and Go. I’m really impressed with the platform so far - it’s awesomely documented and super easy to use. I was impressed to the point I’ve decided to move my blog from a VPS to Google Cloud Storage just to see how it goes.
