- Permasalahan

Karena bikin custom error pages di docker swarm itu susah, seperti biasa, saya maksimalkan saja di image containernya.

- How To

Anda bisa mencari error pages gratisan di github, kalau saya pake punya tarampampam/error-pages. Yang perlu diperhatikan adalah

  1. Copy error pages di folder yang sama, beri nama _error-pages

  2. Tambahkan RUN mkdir -p /usr/share/nginx/html/errorpages, ganti owner folder chown -R nobody.nobody /usr/share/nginx/html/errorpages lalu pindahkaan error dari root RUN mv _error-pages /usr/share/nginx/html/errorpages/

  3. Ini contohnya

FROM alpine:3.13
LABEL Maintainer="Tim de Pater <code@trafex.nl>" \
      Description="Lightweight container with Nginx 1.18 & PHP-FPM 7.3 based on Alpine Linux." \
      Modified="ipang"

RUN apk --no-cache add \
  curl \
  nginx \
  php8 \
  php8-ctype \
  php8-curl \
  php8-dom \
  php8-fpm \
  php8-gd \
  php8-intl \
  php8-json \
  php8-mbstring \
  php8-mysqli \
  php8-opcache \
  php8-openssl \
  php8-phar \
  php8-session \
  php8-xml \
  php8-xmlreader \
  php8-zlib \
  php8-pdo_mysql \
  curl \
  tzdata \
  supervisor \
  && rm /etc/nginx/conf.d/default.conf
