See Snapcraft.yaml reference for full list of supported properties.

  • Build snap using snapcraft command
  • Install newly created snap with sudo snap install --dangerous --devmode myapp_1.0.0_amd64.snap

snapcraft.yaml file in non-standard subdirectory

Snapcraft normally expect snapcraft.yaml file in snap directory. If your project has packaging for multiple other packaging formats, then you need to use build workaround script. Such shell script can put into directory like myapp/install/snap/local as file.

ln -s install/snap ../../../snap
pushd ../../..
rm ../../../snap

Register app in snap store

Setup build on Launchpad

Snap packages can be built automatically on Launchpad. Open Create snap package link form your application branch page.
