Automated Deployment

We use CircleCI to automatically create builds based upon git tags.

  1. run yarn release --dry-run - Note if the output version tag/changelog is correctly generated.
  2. run yarn release - This will generate the changelog, update the version in package.json and create and push a tag.
  3. The deploys jobs will be triggered and upload the artifacts to Github Release page as a draft.

Manual Deployment: macOS

  1. Export the following variables:
    1. CSC_LINK - This is the path to the .p12 certificate file
    2. CSC_KEY_PASSWORD - This is the password of the .p12 certificate file
    3. CSC_IDENTITY_AUTO_DISCOVERY - Set to false to disable usage of local keychain (By default it looks in your login keychain)
    4. GH_TOKEN - This is used to upload the artifacts to Github
  2. Create the distributable, i.e. yarn dist.
  3. Locate and upload the following files as these are required for the auto-updater to work:
    1. dist/nOS-1.0.0-mac.zip
    2. dist/nOS-1.0.0-mac.dmg
    3. dist/nOS-1.0.0-mac.dmg.blockmap
    4. dist/latest-mac.yml

Manual Deployment: Linux

  1. Create the distributable, i.e. yarn dist.
  2. Locate and upload the following files as these are required for the auto-updater to work:
    1. dist/nOS-1.0.0-linux-amd64.snap
    2. dist/nOS-1.0.0-linux-x86_64.AppImage
    3. dist/latest-linux.yml

Manual Deployment: Windows

  1. Export the following variables:
    1. WIN_CSC_LINK - This is the certificate file in text format
    2. WIN_CSC_KEY_PASSWORD - This is the password of the certificate file
    3. GH_TOKEN - This is used to upload the artifacts to Github
  2. Create the distributable, i.e. yarn dist.
  3. Locate and upload the following files as these are required for the auto-updater to work:
    1. dist/nOS-1.0.0-win.exe
    2. dist/nOS-1.0.0-win.exe.blockmap
    3. dist/latest.yml

Generating hashes for the artifacts

  • MacOS/Linux: shasum -a 256 ./* - Where the final argument is the location of the artifacts
