Docker COPY command not copying a specific file - docker

Question

I have a folder dist having config.yaml, configuration.d.ts ,configuration.js and configuration.map files inside. The issue is all files are copied to container except the config.yaml file.
On debugging I found, If I write COPY dist dist before the line FROM abcd.com/baseos/node:buster-14.15.4-1 the config.yanl works. But I write COPY dist dist after the line FROM abcd.com/baseos/node:buster-14.15.4-1 it doesn't copy the config.yaml file but copies all other files configuration.d.ts ,configuration.js and configuration.map
The command to build my Dockerfile is below:-
docker build -t drs:1.0.0 -f . /srs/sync-data
Below is my Dockerfile
FROM abcd.com/baseos/node:buster-14.15.4-1 AS buildcontainer
COPY src src
COPY config config
COPY package*.json ./
COPY tsconfig.json .
COPY tsconfig.build.json .
COPY .eslintrc.js .
COPY .prettierrc .
RUN npm ci && \
npm run build && \
rm -rf node_modules && \
npm ci --production
FROM abcd.com/baseos/node:buster-14.15.4-1
ARG SERVICEVERSION=0.0.0-snapshot
ENV SERVICEVERSION=$SERVICEVERSION
COPY --from=buildcontainer dist dist
COPY --from=buildcontainer node_modules node_modules
COPY package.json .
CMD npm run start:prod

Since I'm using nestjs, I didn't copied over nest-cli.json in dockerfile. My nest-cli.json had below config:-
"compilerOptions": {
"assets": [{"include": "../config/*.yaml", "outDir": "./dist/config"}]
}
which tells the nest compiler to put it into dist folder.
Once I added below line in Dockerfile, it worked.
COPY .nest-cli.json .
