Resolving Kubernetes Pod has unbound PersistentVolumeClaims Error

Hi guys, I found a problem with volume configuration error during kubernetes container initialization. I tried a lot of way to solve this problem such as creating longhorn provisioner and local path and node but these ways didn't resolve problem on initialization. I used nfs-server-provisioner catalog app for helm and i see a new storage class named nfs. I remove my another storage classes to force new apps to use this storage class. This worked like a charm! Now i can install all of catalog apps without any persistence and volume based problem.

rancher kubernetes Failed to make shared /var/lib/rancher/volumes: invalid argument error

Hi,
If you downgrade rancher 2.0 to 1.x and getting this error with kubernetes you can just reboot physical server:)

curl: (35) gnutls_handshake() failed: Error in the pull function error on docker installation

Hi everyone,
If you get curl: (35) gnutls_handshake() failed: Error in the pull function. error on docker installation and if you removed older and fewer versions before you just have to remove old ppa from your hosts /etc/apt/sources.list

For do this open /etc/apt/sources.list with vi, nano etc. and comment all deb source lines by adding # character to start of line. You can also see example of comment in file.

After remove or comment source you have to apt-get update to apply changes and you can install docker version what if you want!

good luck
