## Install required dependencies for the build
RUN apt-get update && apt-get install libxml2-dev libsqlite3-dev -y

## Allow the usage of private repository
### This part is for advanced user, ignore it if you don't use private repository in Swift package manager
## 1. Add SSH Hostname to known_host (This is use for Private repo in SPM)
## Here we add github.com hostname as when building the docker file we don't have an interactive shell
## It means it will be known from git, so won't request confirmation of the key
## You may want to add your own
## 2. It will use you private keys to clone private repository
## You private keys should be stored (Password less, decrypted) in the folder `ssh`
## for Continous integration, you will need a step to copy the decrypted key to the folder. Symbolic link won't work
RUN if [ -d "ssh" ]; then \ 
 mkdir -p ~/.ssh/; \
 eval `ssh-agent`; \
 ssh-keyscan -H github.com  >> ~/.ssh/known_hosts; \

## Build the application
RUN echo "---> Build application"; \

    ssh-add ssh/*; \

## Organizing things up
RUN mkdir -p /tmp/app

## Check if the folder contains preexising DB/Folders.
## It means the user may have prepare Feather-CMS locally, in that case we will copy its content to the template folder
## So the user will keep what he prepared
RUN cd /opt/feather; if [ -f "db.sqlite" ]; then cp -pr db.sqlite /tmp/app; fi

## Prepare entry point

## Keep only executables & resources (will be available in /opt/feather/bin )
RUN mv /opt/feather/.build/x86_64-unknown-linux-gnu/release /tmp/app/bin

## Copy any custom scripts under the `customscripts` folder
## If the user decide to use a diffent enty point from start, he can create hsi own scripts. 
## Ex. We could imagine, starting 10 servers in one docker. The script would set, different folders, env variables. It will not work with embeded DB here...
## docker run -d -p 8080-8090:8080-8090 feather start_10_apps

## Clean up & keep only executbale from the build
RUN cd /; rm -rf /opt/feather; mv /tmp/app /opt/feather
