Oke Jenkins sudah running, selanjutnya akses menggunakan browser ke IP Public instance. Jika belum bisa di akses seperti gambar di bawah ini maka kita harus setting security instance nya untuk allow port 8080.

Ke bagian Security Groups, Edit Inbound tambahkan seperti ini. Save rules

balik ke browser lagi akses menggunakan port 8080

untuk unlock jenkins kita harus membuka file /var/lib/jenkins/secrets/initialAdminPassword di instance.

copy kan password ke dalam kolom Administrator password tersebut dan continue.

Pilih saja install suggested plugins nanti akan di install plugin2 yang biasa nya di perlukan. Masukan username, password dan full name. Save and continue.

sampai di sini pastikan URL sama dengan yang link browser di atas nya. save and finish

Yey Start using jenkins !!
