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.

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]

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.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].
