Docker: ERROR: Job failed: command terminated with exit code 1

I am trying to copy all the files from a folder into a folder within a docker image as it's being built. Here is my error from my gitlab pipeline when it tries to build the docker image.

Status: Downloaded newer image for nginx:1.18.0-alpine
 ---> 8c1bfa967ebf
Step 2/3 : COPY conf/default.conf /etc/nginx/conf.d/default.conf
COPY failed: Forbidden path outside the build context: ../../src/ ()
 ---> ffbb72db6c26
Step 3/3 : COPY ../../src/ /var/www/html/public
ERROR: Job failed: command terminated with exit code 1

Here is the dockerfile + folder structure

My gitlab-ci.yml file:

image: docker:stable

services:
- docker:18-dind
variables:
  DOCKER_HOST: tcp://localhost:2375

php:

  before_script:
    - docker login gitlab.domain.com:5050 -u ${CI_REGISTRY_USER} -p ${CI_REGISTRY_PASSWORD}
  script:
    - docker build -t gitlab.domain.com:5050/project/php:7.2-fpm ./php-fpm
    - docker push gitlab.domain.com:5050/project/php:7.2-fpm

nginx:

  before_script:
    - docker login gitlab.domain.com:5050 -u ${CI_REGISTRY_USER} -p ${CI_REGISTRY_PASSWORD}
  script:
    - docker build -t gitlab.domain.com:5050/project/nginx:stable ./nginx
    - docker push gitlab.domain.com:5050/project/nginx:stable

Straight from the docker documention

The path must be inside the context of the build; you cannot COPY ../something /something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.

As an alternative, you can update the directory structure like this:

- code
  - nginx
  - php-fpm
  - src
  - Dockerfile

Then update the source path for COPY command in Dockerfile.

Updated Dockerfile:

FROM
RUN

COPY php-fpm/php-fpm.d/entrypoint.sh /usr/local/bin/
COPY src/ /var/www/html/public/src/

WORKDIR
CMD

COPY adds files from your Docker client’s current directory.

from https://docs.docker.com/engine/reference/builder/

COPY obeys the following rules:

The <src> path must be inside the context of the build; you cannot COPY ../something /something, 
because the first step of a docker build is to send the context directory (and subdirectories) 
to the docker daemon.

If <src> is a directory, the entire contents of the directory are copied, 
including filesystem metadata.

so please restructure the docker project structure and COPY the content inside the current directory structure.
