Azure

NOT PORTED YET

DevOps Bash tools for Azure, AKS, VMs etc

Follow the install doc or paste this to run an automated install script which auto-detects and handles Mac or Linux:

git clone https://github.com/HariSekhon/DevOps-Bash-tools

bash-tools/install/install_azure_cli.sh

Then authenticate using one of the documented methods eg:

az login

First set up your Azure CLI as above.

Run the aks_kube_creds.sh script from the DevOps-Bash-tools repo's azure directory.

This will find and configure all your kubernetes clusters in the current project.

az aks get-credentials --resource-group myResourceGroup --name myAKSCluster

kubectl config get-contexts

switch to the cluster you want:

kubectl config use-context <name>

kubectl get pods --all-namespaces

Then see Kubernetes for configs, scripts and .envrc.

Data is always replicated 3x in primary region. Options:

LRS (locally-redundant storage)
- replicates within same AZ - not recommended for HA or durability
- 11 nines durability
- synchronously writes to all 3 replicas
ZRS (zone-redundant storage)
- multi-zone - replicates to 3 AZs
- 12 nines durability
- synchronously writes to all 3 replicas
- app still needs transient fault handling to account for DNS failover time - retry policies with exponential back-off
- use this - price is ~50% more but still fairly trivial in overall cost compared to the compute its attached to eg. spending only $15 a month on a 100GB storage disk SSD for a $450 a month VM with 8vCPUs and 64GB RAM.
