Lanjut dari Session 1 sampai di sini kita akan menjalankan web service atlantis. Untuk menjalankan web service Atlantis kita akan membuat Systemd Service.

Create Systemd Service

$ cd /etc/systemd/system
$ sudo nano atlantis.service

isi dengan

[Unit]
Description=service automation atlantis pull request

[Service]
ExecStart= atlantis server --atlantis-url="http://ippublicserver" --gh-user="user github" --gh-token="token personal github" --gh-webhook-secret="secret yang tadi di buat diwebhook" --repo-allowlist="url repository" --port=80 --repo-config="/home/ubuntu/atlantis-config.yaml"
Restart=always

[Install]
WantedBy=multi-user.target

selanjut nya di server kita bikin file atlantis-config.yaml

$ cd /home/ubuntu
$ nano atlantis-config.yaml

isi dengan

repos:
- id: /.*/
 workflow: terragrunt
workflows:
 terragrunt:
  plan:
   steps:
   - env:
     name: DESTROY_PARAMETER
     command: if [ "$COMMENT_ARGS" = "\-\d\e\s\t\r\o\y" ]; then echo "-destroy"; else echo ""; fi
   - run: terragrunt plan --terragrunt-non-interactive -no-color -out=$PLANFILE $DESTROY_PARAMETER
  apply:
   steps:
   - run: terragrunt apply --terragrunt-non-interactive -no-color $PLANFILE

jangan lupa untuk reload service yang sudah di buat tadi

$ sudo systemctl daemon-reload
$ sudo systemctl start atlantis
$ sudo systemctl status atlantis
atlantis.service - service automation atlantis pull request
     Loaded: loaded (/etc/systemd/system/atlantis.service; disabled; vendor preset: enabled)
     Active: active (running) since Sat 2022-12-31 10:46:42 UTC; 30s ago
   Main PID: 25724 (atlantis)
      Tasks: 7 (limit: 2309)
     Memory: 9.0M
     CGroup: /system.slice/atlantis.service

coba akses menggunakan ip publik server, jika terjadi error coba cek security group di AWS EC2 instance nya apakah port 80 sudah di accept lewat publik. Jika sudah tampilan awal seperti ini.

next push configuration terraform ke github.

Configure AWS CLI

$ sudo apt install awscli
$ aws configure --profile aws-staging //proses staging
//* login aws *//
//* access key *//
//* secret key *//

Create bucket storage (S3)

pergi ke AWS Console > search S3. buat nama unik dan create bucket. AWS S3 di butuhkan untuk menyimpan state, database terraform.
