Custom apps

To add your own Frappe/ERPNext apps to the image, we'll need to create a custom image with the help of a unique wrapper script

For the sake of simplicity, in this example, we'll be using a place holder called [custom], and we'll be building off the edge image.

Create two directories called [custom]-worker and [custom]-nginx in the build directory.

cd frappe_docker
mkdir ./build/[custom]-worker ./build/[custom]-nginx

Create a Dockerfile in ./build/[custom]-worker with the following content:

FROM frappe/erpnext-worker:edge

RUN install_app [custom] https://github.com/[username]/[custom] [branch]
# Only add the branch if you are using a specific tag or branch.

Note: Replace https://github.com/[username]/[custom] above with your custom app's Git repository URL (may include credentials if needed). Your custom app Git repository must be named exactly as the custom app's name, and use the same branch name as Frappe/ERPNext branch name that you use.

Create a Dockerfile in ./build/[custom]-nginx with the following content:

FROM bitnami/node:12-prod

COPY build/[custom]-nginx/install_app.sh /install_app

RUN /install_app [custom] https://github.com/[username]/[custom] [branch]

FROM frappe/erpnext-nginx:edge

COPY --from=0 /home/frappe/frappe-bench/sites/ /var/www/html/
COPY --from=0 /rsync /rsync
RUN echo -n "\n[custom]" >> /var/www/html/apps.txt

VOLUME [ "/assets" ]

ENTRYPOINT ["/docker-entrypoint.sh"]
CMD ["nginx", "-g", "daemon off;"]

Copy over the install_app.sh file from ./build/erpnext-nginx

cp ./build/erpnext-nginx/install_app.sh ./build/[custom]-nginx

Open up ./installation/docker-compose-custom.yml and replace all instances of [app] with the name of your app.

sed -i "s#\[app\]#[custom]#" ./installation/docker-compose-custom.yml

Install like usual, except that when you set the INSTALL_APPS variable to erpnext,[custom].
