Project Infrastructure :

How To Deploy This Solution:

01- Clone The Repository On Your Bastion Machine :

02- Run Terraform Apply Inside ProjectC/Infra

03- Deploy Apps Using ArgoCD In The Bellow Order :

• Wordpress Blue/Green

• Nginx Ingress Controller

• Microservices Blue/Green

• To get ArgoCD Secret:

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

• To expose argocd-server service, ane get access to it using your EC2 Bastion PublicIP.

kubectl port-forward svc/argocd-server -n argocd 4001:443 --address 0.0.0.0

ArgoCD Workflow:

04- Vault Server Configuration :

Vault Architecture:

• Connect to your Vault Server via SSH.

• Run:

sudo nano /etc/vault.d/vault.hcl

Past the configuration bellow on it:

storage "raft" {
  path    = "/opt/vault/data"
  node_id = "raft_node_1"
}

listener "tcp" {
  address     = "0.0.0.0:8200"
  tls_disable = 1
}

api_addr = "http://127.0.0.1:8200"
cluster_addr = "https://127.0.0.1:8201"
ui = true

• Run the followings commands in order:

sudo systemctl start vault

sudo systemctl stop vault

sudo systemctl start vault

• Now we should add the ip addr of our Vault Server to our env:
• Open ".profile" by running : "sudo nano ~/.profile" and add the bellow line in it:

export VAULT_ADDR='http://127.0.0.1:8200'

• Now run : "source ~/.profile" to load your env.
• If you would to check that you did everything correctly run: "env | grep VAULT_ADDR".
• Now you can initilize your Vault Server by running, you should get 5 KEYs and login_token (SAVE THEM IN A SAFE PLACE) :

vault operator init

• Now we have to UNSEAL our Vault Server by running this command 3 TIMES, and enter the secrets that we got early "WE NEED JUST 3 SECRETS":

vault operator unseal

• After checking that the SEAL is FALSE.

Vault Sealed Mode=TRUE:

Vault Sealed Mode=FALSE:

• We Can Login Now:

vault login login_token

• Now we'll enable the AppRole Auth Mehod:

vault auth enable approle

• After it we have to create the role for Jenkins and make it usage illimit :

vault write auth/approle/role/jenkins-role token_num_uses=0 secret_id_num_uses=0 policies="jenkins"

• To get the RoleID and the RoleSecret_ID, We'll add the values later to our Jenkins Credentials :

vault read auth/approle/role/jenkins-role/role-id

vault write -f auth/approle/role/jenkins-role/secret-id

• Now we can enable The Secrets of type "KeyValues" :

vault secrets enable -path=secrets kv

• Finally, we'll create a Policy for our AppRole, to be able to wread all the secrets on this path "secrets/creds/":

nano jenkins-policy.hcl

path "secrets/creds/*" {
 capabilities = ["read"]
}

• If you did everything correctly, you'll be able to write your KV now:

1- First KV, is the credentials of our BuildingMachine (Jenkins Agent).

vault write secrets/creds/ec2_abdelatif username=ubuntu private_key="$(cat /home/ubuntu/key.pem)" passphrase=

2- The Second KV, will be the microservices Secrets:

vault write secrets/creds/microservices MYSQL_DATABASE_USER=<value> MYSQL_DATABASE_PASSWORD="<value>" MYSQL_DATABASE_DB=<value> dbport="<value>" productapiurl="https://projetc.abdelatif-aitbara.link/wp-json/wc/v3/products" orderapiurl="https://projetc.abdelatif-aitbara.link/wp-json/wc/v3/orders" customerapiurl="https://projetc.abdelatif-aitbara.link/wp-json/wc/v3/customers" MYSQL_DATABASE_HOST=<value> secretkey="<value>" consumerkey=<value> consumersecret=<value> ecr-username="AWS" ecr-repository="<value>" k6token="<value>"

05- Jenkins Configuration :

CI/CD Overview:

CI Workflow:

0- Install plugins :

Vault
Snyk
Blueocean

2- Add JavaPath to JDK TOOLS: /usr/bin/java

2- Configure VAULT SERVER, Add Vault Credentials, VAULT APP ROLE.

3- Add Agents Credentials ( user, pairkey, passphrase )

4- Configure Agents ( You have to add the keypair in your Vault before )

5- Add SSH-Public Key OF JENKINS CONTAINER to GitHub And Add IT TO BM :

ssh-keygen -t ed25519 -C "your_email"

ssh-keyscan github.com >> ~/.ssh/known_hosts

6- Configure Snyk Installation ( TOOLS ) and add a new TOKEN (Credentials),

7- Change the IP OF OUR VAULT ON Jenkinsfile

8- Add EC2 Jenkins Public Dns To Your GitHub Webhook.

9- Create "Microservices" and "GitOps" Pipelines.

ArgoCD WorkFlow:

07- Add Let's Encrypt Certificate To ACM :

1- Export Normal tls.crt and tls.key ( this issuer key)
2- Make a combination between them on : tls-combinated.crt 

- At the beginning put the key part (goted from issuer ) and after the cert part
- after it convert it to .pem

3- openssl x509 -in tls.crt -out cert.pem
