Snapcraft

GoReleaser can also generate snap packages. Snaps are a new packaging format, that will let you publish your project directly to the Ubuntu store. From there it will be installable in all the supported Linux distros, with automatic and transactional updates.

You can read more about it in the snapcraft docs.

Available options:

# .goreleaser.yml
snapcrafts:
  -
    # ID of the snapcraft config, must be unique.
    # Defaults to "default".
    id: foo

    # Build IDs for the builds you want to create snapcraft packages for.
    # Defaults to all builds.
    builds:
    - foo
    - bar

    # You can change the name of the package.
    # Default: `{{ .ProjectName }}_{{ .Version }}_{{ .Os }}_{{ .Arch }}{{ if .Arm }}v{{ .Arm }}{{ end }}{{ if .Mips }}_{{ .Mips }}{{ end }}`
    name_template: "{{ .ProjectName }}_{{ .Version }}_{{ .Os }}_{{ .Arch }}"

    # Replacements for GOOS and GOARCH in the package name.
    # Keys should be valid GOOSs or GOARCHs.
    # Values are the respective replacements.
    # Default is empty.
    replacements:
      amd64: 64-bit
      386: 32-bit
      darwin: macOS
      linux: Tux

    # The name of the snap. This is optional.
    # Default is project name.
    name: drumroll

    # Wether to publish the snap to the snapcraft store.
    # Remember you need to `snapcraft login` first.
    # Defaults to false.
    publish: true

    # Single-line elevator pitch for your amazing snap.
    # 79 char long at most.
    summary: Software to create fast and easy drum rolls.

    # This the description of your snap. You have a paragraph or two to tell the
    # most important story about your snap. Keep it under 100 words though,
    # we live in tweetspace and your description wants to look good in the snap
    # store.
    description: This is the best drum roll application out there. Install it and awe!

    # A guardrail to prevent you from releasing a snap to all your users before
    # it is ready.
    # `devel` will let you release only to the `edge` and `beta` channels in the
    # store. `stable` will let you release also to the `candidate` and `stable`
    # channels. More info about channels here:
    # https://snapcraft.io/docs/reference/channels
    grade: stable

    # Snaps can be setup to follow three different confinement policies:
    # `strict`, `devmode` and `classic`. A strict confinement where the snap
    # can only read and write in its own namespace is recommended. Extra
    # permissions for strict snaps can be declared as `plugs` for the app, which
    # are explained later. More info about confinement here:
    # https://snapcraft.io/docs/reference/confinement
    confinement: strict

    # Your app's license, based on SPDX license expressions: https://spdx.org/licenses
    # Default is empty.
    license: MIT

    # A snap of type base to be used as the execution environment for this snap.
    # Valid values are:
    # * bare - Empty base snap;
    # * core - Ubuntu Core 16;
    # * core18 - Ubuntu Core 18.
    # Default is empty.
    base: core18

    # Add extra files on the resulting snap. Useful for including wrapper
    # scripts or other useful static files. Source filenames are relative to the
    # project directory. Destination filenames are relative to the snap prime
    # directory.
    # Default is empty.
    extra_files:
      - source: drumroll.wrapper
        destination: bin/drumroll.wrapper
        mode: 0755

    # With layouts, you can make elements in $SNAP, $SNAP_DATA, $SNAP_COMMON
    # accessible from locations such as /usr, /var and /etc. This helps when using
    # pre-compiled binaries and libraries that expect to find files and
    # directories outside of locations referenced by $SNAP or $SNAP_DATA.
    # About snap environment variables:
    # * HOME: set to SNAP_USER_DATA for all commands
    # * SNAP: read-only install directory
    # * SNAP_ARCH: the architecture of device (eg, amd64, arm64, armhf, i386, etc)
    # * SNAP_DATA: writable area for a particular revision of the snap
    # * SNAP_COMMON: writable area common across all revisions of the snap
    # * SNAP_LIBRARY_PATH: additional directories which should be added to LD_LIBRARY_PATH
    # * SNAP_NAME: snap name
    # * SNAP_INSTANCE_NAME: snap instance name incl. instance key if one is set (snapd 2.36+)
    # * SNAP_INSTANCE_KEY: instance key if any (snapd 2.36+)
    # * SNAP_REVISION: store revision of the snap
    # * SNAP_USER_DATA: per-user writable area for a particular revision of the snap
    # * SNAP_USER_COMMON: per-user writable area common across all revisions of the snap
    # * SNAP_VERSION: snap version (from snap.yaml)
    # More info about layout here:
    # https://snapcraft.io/docs/snap-layouts
    # Default is empty.
    layout:
      # The path you want to access in sandbox.
      /etc/drumroll:

        # Which outside file or directory you want to map to sandbox.
        # Valid keys are:
        # * bind - Bind-mount a directory.
        # * bind_file - Bind-mount a file.
        # * symlink - Create a symbolic link.
        # * type - Mount a private temporary in-memory filesystem.
        bind: $SNAP_DATA/etc

    # Each binary built by GoReleaser is an app inside the snap. In this section
    # you can declare extra details for those binaries. It is optional.
    apps:

      # The name of the app must be the same name as the binary built or the snapcraft name.
      drumroll:

        # If your app requires extra permissions to work outside of its default
        # confined space, declare them here.
        # You can read the documentation about the available plugs and the
        # things they allow:
        # https://snapcraft.io/docs/reference/interfaces.
        plugs: ["home", "network", "personal-files"]

        # If you want your app to be autostarted and to always run in the
        # background, you can make it a simple daemon.
        daemon: simple

        # If you any to pass args to your binary, you can add them with the
        # args option.
        args: --foo

        # Bash completion snippet. More information about completion here:
        # https://docs.snapcraft.io/tab-completion-for-snaps.
        completer: drumroll-completion.bash

        # You can override the command name.
        # Defaults is the app name.
        command: bin/drumroll.wrapper

        # Restart condition of the snap.
        # Defaults to empty.
        # https://snapcraft.io/docs/snapcraft-yaml-reference
        restart_condition: "always"

    # Allows plugs to be configured. Plugs like system-files and personal-files
    # require this.
    # Default is empty.
    plugs:
      personal-files:
        read:
        - $HOME/.foo
        write:
        - $HOME/.foo
