i am getting CrashLoopBackOff error "exec /usr/sbin/nginx", how to resolve?

Question

This is my docker file

#!/bin/bash
FROM node:10.8.0 as build-stage
WORKDIR /app
COPY package*.json /app/
RUN npm install
COPY ./ /app/
ARG configuration=production
RUN npm run build -- --output-path=./dist/out --configuration $configuration
FROM nginx:1.15
#Copy ci-dashboard-dist
COPY --from=build-stage /app/dist/out/ /usr/share/nginx/html
#Copy default nginx configuration
COPY ./nginx-custom.conf /etc/nginx/conf.d/default.conf

I am getting error CrashLoopBackOff. When i try to find the log it says exec /usr/sbin/nginx: exec format error. How can i resolve this and get the app running

Are you potentially building the image on an ARM-based system (like an M1 Mac) but running it on an x86 host, or vice versa? — David Maze

Try something like adding --platform=linux/amd64 in your Dockerfile

FROM --platform=linux/amd64 node:18-alpine as builder

Build the image and run it on K8s.

it could be due to the building image on Mac or Arm and your K8s cluster is not supporting that architecture.

The optional --platform flag can be used to specify the platform of the image in case FROM references a multi-platform image. For example, linux/amd64, linux/arm64, or windows/amd64. By default, the target platform of the build request is used.
