KubeRider :: Bundling MacOS release
In this post, I’ll go through what is involved in building a MacOS release package and publishing it on Github from TravisCI.
Step 1: Application Icon
Although it is probably quicker to find/generate a logo from an online service. I decided to create a simple logo to go through the process of creating and converting it in vector drawing.
Here is what I ended up using the Paper app on iPad.
The next step is to convert it in vector which is easy once you managed to install Inkscape.
Now that the SVG file is exported, I have a helper script to generate iconset using Inkscape.
#!/usr/bin/env bash
inkscape="/Applications/Inkscape.app/Contents/Resources/bin/inkscape"
svg_file=$1
output_name=$2
set -e
test -d "$output_name.iconset" && rm -R "$output_name.iconset"
mkdir "$output_name.iconset"
$inkscape -z -e "$PWD/$output_name.iconset/icon_16x16.png" -w 16 -h 16 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_16x16@2x.png" -w 32 -h 32 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_32x32.png" -w 32 -h 32 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_32x32@2x.png" -w 64 -h 64 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_128x128.png" -w 128 -h 128 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_128x128@2x.png" -w 256 -h 256 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_256x256.png" -w 256 -h 256 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_256x256@2x.png" -w 512 -h 512 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_512x512.png" -w 512 -h 512 "$svg_file"
$inkscape -z -e "$PWD/$output_name.iconset/icon_512x512@2x.png" -w 1024 -h 1024 "$svg_file"
iconutil -c icns "$output_name.iconset"
rm -R "$output_name.iconset"
mv $output_name.icns packaging/data/icons/
$inkscape -z -e "$PWD/${output_name}/images/${output_name}.png" -w 512 -h 512 "$svg_file"
Then we simply run the above script providing it the path to the svg file
./mk-icns.sh `pwd`/kuberider/images/kuberider.svg kuberider
That generates an icon set and an image which will be used during package installation.
Step 2: Building an Apple Disk Image (dmg) file
The setup.py uses py2app to generate an .app file for MacOS and Node AppDmg package to produce the DMG file.
Step 3: Publishing from TravisCI to Github
The release pipeline is separated into two different Github repos so that I can control the release process. The kube-rider-osx repo contains the .travis.yml file to download the release and prepare the toolchain to generate and publish the release.
Once successfully built, TravisCI publishes the new release on Github
