Unable to COPY config file in nginix /etc/nginx/conf.d/default.conf

javascript reactjs docker nginx config

If the source file path is /app/nginix.conf then dockefile should contain:

COPY /app/nginx.conf /etc/nginx/conf.d/default.conf

If you're running docker build command from /app directory on your host then your above dockerfile should work.

Update:

If you're expecting /app/nginx.conf file of node docker image to present in nginx:alpine image then you need to use multi-stage docker builds.

Change your dockerfile to

FROM node as build
WORKDIR /app
COPY package json files 
RUN npm build

FROM nginx:alpine 
COPY --from=build /app/nginx.conf /etc/nginx/conf.d/default.conf

This will copy /app/nginx.conf file from node image to nginx:alpine image.

Unable to Copy config file in my project dir to /etc/nginx/conf.d/default.conf

source file location: /app/nginix.conf

COPY nginx.conf /etc/nginx/conf.d/default.conf

destination : /etc/nginx/conf.d/default.conf

Steps in docker file :
```
Tried the multi stage build:

- FROM node:8.9.0 as buid
- WORKDIR /app
- COPY package.json package-lock.json ./
- RUN npm install
- COPY . ./
- RUN npm run build


- FROM nginx:alpine
- RUN mkdir -p /var/www/html/client
- COPY --from=buid /app/nginix.conf /etc/nginx/conf.d/default.conf
- COPY --from=buid /app/build/ /var/www/html/client
```
Tried commenting the first copy command, and it was able to copy the build and it was good. when it is able to find the build in the app dir why is it not able to find the nginix.conf file which is also in the same dir, did a ls -la and saw the nginix.conf file.

TIA

  On your local system, is nginx.conf in the same directory as your Dockerfile?

  yes, Docker file and nginix.conf both are in the same directory.

I tried the same : COPY failed: stat /var/lib/docker/tmp/docker-builder-number/app/nginx.conf: no such file or directory. After reaching this point: FROM nginix:alpine the dir is changing am not able to figure that out.

- FROM node - WORKDIR /app - COPY package json files - RUN npn build I tried pwd and ls -la, I could see all my project files and my config file as well FROM nginix:alpine not sure whats going on after this point.

Does that nginx.conf file gets created in FROM node image in /app folder which you want that in FROM nginx:alpine image.

I want that from /app folder, but when am doing FROM nginx:alpine, the root is getting changed and not able to find the nginix.conf file.
