Default Environment Variables
20 min read
Environment variable digunakan untuk menyimpan nilai dari parameter-parameter yang sering dipakai, yang diberikan ke program saat dijalankan. Penggunaan variabel semacam ini bikin aplikasi Kamu jadi lebih fleksibel dan gampang dipindahkan ke tempat lain (portabel).
Penggunaan variabel yang paling umum adalah untuk mempermudah mengubah nilai-nilai tertentu yang sering digunakan di banyak bagian kode. Selain itu, variabel juga sering dipakai untuk mengatur perilaku aplikasi lewat nilai-nilai yang sudah ditentukan sebelumnya — misalnya untuk mengaktifkan/menonaktifkan fitur, atau mengubah cara aplikasi bekerja. Di platform ini, sebagian besar stack aplikasi resmi (certified stacks) sudah dilengkapi dengan variabel default yang bisa langsung kamu manfaatkan untuk mempermudah proses hosting aplikasi.

📝 NOTE
Variabel yang diberi tanda “+” pada kolom Editable berarti bisa Kamu ubah sesuka hati untuk menyesuaikan konfigurasi container-mu. Tapi, setelah kamu mengubahnya, kamu perlu restart container agar perubahan tersebut berlaku.Sementara itu, variabel yang diberi tanda “–” sebaiknya jangan diubah. Karena meskipun Kamu ganti nilainya, perubahan itu tidak akan benar-benar diterapkan ke container, dan malah bisa membuat beberapa fungsi internal menjadi error.
