Running the code

We use Docker and Docker Compose.

You can use the Docker Compose setup if you are using one of the following:

• Linux (64bit)
• OSX Yosemite 10.10.3 or higher
• Windows 10 Pro or higher

If you are not using one of those, then try the Vagrant + Docker Compose setup.

Linux

Install Docker CE.

And make sure you have Docker Compose (at least version 1.6.0) installed too (often comes with Docker).

The current version of Fedora 31 switched to using cgroupsV2 by default, which is not yet supported.

To disable v2 cgroups, run:

sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0"

And restart your machine.

If you cannot connect to Docker with your local user, then you may want to add yourself to the Docker group:

sudo usermod -aG docker $USER

# then either log in again to reload the groups
# or run (for each shell...)
su - $USER

# should now be able to connect without errors
docker info

Then:

git clone git@gitlab.com:foodsharing-dev/foodsharing.git foodsharing
cd foodsharing
./scripts/start

OSX Yosemite 10.10.3 or higher

Install Docker for Mac (direct link).

Then:

git clone git@gitlab.com:foodsharing-dev/foodsharing.git foodsharing
cd foodsharing
./scripts/start

Windows

If you are using Windows 10 Pro or higher go with this link:

Install Docker for Windows (direct link) and Git for Windows.

If you are using Windows 10 Home or lower follow this instruction:

Install [Docker Toolbox for Windows] (https://docs.docker.com/toolbox/toolbox_install_windows/) and Git for Windows.

It is important to grant docker access to C: (in the graphical docker interface: settings -> resources -> filesharing -> mark C, apply and restart)

You can test your docker in the command shell (e.g. cmd or powershell) with the command docker --version. If it shows something, you're good to go.

Restart your Windows now.

There is a graphical user interface to administrate the repo, which is recommended for Git beginners.

But you can use the Git Bash shell just like in Linux to clone it:

git clone git@gitlab.com:foodsharing-dev/foodsharing.git foodsharing

After this command, your files will be found in the folder %UserProfile%\foodsharing

To start the containers, use the Git Bash shell:

cd foodsharing
./scripts/start

The first time you run the start script, which takes a lot of time, you probably have to give the windows firewall the OK to let Docker work.

Known Issues on Windows

• general

If something is wrong, please check in your task manager under "performance" if the virtualisation is activated and troubleshoot if necessary.

• [RuntimeException]

If you get a [RuntimeException], let ./scripts/start run again and again and maybe even again until it's done.

• yarn lint

There is a known bug concerning yarn, see: https://github.com/yarnpkg/yarn/issues/7187 and https://github.com/yarnpkg/yarn/issues/7732 and https://github.com/yarnpkg/yarn/issues/7551

• Changes in js, vue etc. aren't showing up

In order to have the webpack-dev-server recognize changes you have to add this watchOptions block to client/serve.config.js

[...]
module.exports = {
  [...]
  devServer: {
    watchOptions: {
      poll: true
    },
    [...]

Note: Please make sure not to commit this file afterwards with your changes.

Vagrant

If you cannot use any of the above methods, then this should work with every common operation system.

However, we are less familiar with this solution, so we may be less able to support you.

Install VirtualBox and Vagrant.

Then:

git clone git@gitlab.com:foodsharing-dev/foodsharing.git foodsharing
cd foodsharing
vagrant up

Daily work

vagrant up starts the machine and foodsharing project.

vagrant halt stops the virtual machine.

vagrant ssh connects to the virtual machine.

Once connected to the virtual machine, go to /vagrant with cd /vagrant. This is where the foodsharing folder is mounted in the VM. From there on, you can run all scripts with ./scripts/NAME.

Note: ./scripts/start will always be executed, when you start the virtual machine with vagrant up.

There is a known bug when running VirtualBox + nginx that nginx serves files from a memory cache. If you encounter this problem, then it can probably be fixed by emptying the memory cache with sync; sudo sh -c "/bin/echo 3 > /proc/sys/vm/drop_caches" or even running this every second with watch -n 1 'sync; sudo sh -c "/bin/echo 3 > /proc/sys/vm/drop_caches"'.
