After 9 minutes 44 seconds, I got a ready-made self-supporting infrastructure for a Kubernetes cluster:
esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ ./../terraform apply -var = "token = AKIAJ4SYCNH2XVSHNN3A" -var = "key = huEWRslEluynCXBspsul3AkKlin1ViR9 + Mo
Now let's delete (it took me 10 minutes 23 seconds):
esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ ./../terraform destroy -var = "token = AKIAJ4SYCNH2XVSHNN3A" -var = "key = huEWRslEluynCXBspsul3AkKlin1ViR9 + Mo
Destroy complete! Resources: 7 destroyed.
Establishing the CI / CD process
Amazon provides (aws.amazon.com/ru/devops/) a wide range of DevOps tools designed in a cloud infrastructure:
* AWS Code Pipeline – the service allows you to create a chain of stages from a set of services in a visual editor, through which the code must go before it goes to production, for example, assembly and testing.
* AWS Code Build – the service provides an auto-scaling build queue, which may be required for compiled programming languages, when adding features or making changes requires a long re-compilation of the entire application, when using one server it becomes a bottleneck when rolling out the changes.
* AWS Code Deploy – Automates deployment and rollback in case of errors.
* AWS CodeStar – the service combines the main features of the previous services.
Setting up remote control
artifact server
aws s3 ls s3: // name_backet aws s3 sync s3: // name_backet name_fonder –exclude * .tmp # files from the bucket will be downloaded to the folder, for example, a website
Now, we need to download the AWS plugin:
esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ ./../terraform init | grep success
Terraform has been successfully initialized!
Now we need to get access to AWS, for that we click on the name of your user in the header of the WEB interface, in addition to My account , the My Security Credentials item will appear , by selecting which, we go to Access Key -> Create New Access Key . Let's create EKS (Elastic Kuberntes Service):
esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ ./../terraform apply
–var = "token = AKIAJ4SYCNH2XVSHNN3A" -var = "key = huEWRslEluynCXBspsul3AkKlinAlR9 + MoU1ViY7"
Delete everything:
$ ../terraform destroy
Creating a cluster in GCP
node pool – combining nodes into a cluster with
resource "google_container_cluster" "primary" {
name = "tf"
location = "us-central1"
$ cat main.tf # configuration state
terraform {
required_version = "> 0.10.0"
}
terraform {
backend "s3" {
bucket = "foo-terraform"
key
