Terraform mostly used commands

alias tf="terraform"
tf init
tf plan
tf apply
tf destroy
tf refresh
tf workspace list/select

tfenv - terraform version manager, helps to manage multiple versions of terraform.

tfenv list-remote
tfenv install 0.14.11
tfenv use 0.15.1

Popular Deployment strategies

Canary: Version Y is deployed to the subset of users, then released to all.

Blue/Green: Version Y is deployed alongside version X, Once version Y is tested, it takes over the traffic.

AWS Global Accelerator helps to move user's traffic off the internet and onto amazon's private network to increase the response times of the applications.

Since it uses the aws's private network, latency is greatly improved.

👉 kubectl get nodes -o json | jq -c 'path(..)|[.[]|tostring]|join(".")'

☑️Form the jsonpath query

Example:-

✅Continuous deployment :
Every artifact is deployed to non-prod and prod environments automatically.

✅Continuous delivery :
Before deploying to production there's a manual approval required. 👨‍💻
