Release tag version with some artifacts

github-release.sh

#!/bin/sh

### Github create release script
### This script requires following UNIX commands:
### - jq
### - file
### - curl
### - basename
### Those commands might not be installed on CI environment due to tiny OS package,
### So probably you need to install manually.
### For example, on Ubuntu: sudo apt-get install jq file curl

## Configuration for your project

### If you run this script as inline code like Jenkins, define as following:
### But we strongly recommend that specify access token at external environement variable.
#GITHUB_TOKEN="your github access token"

### Directory contains build artifacts if you have.
### If you don't have any artifacts, please keep it empty.
ASSETS_DIR=""

### Determine  project repository
REPOSITORY=":owner/:repo"

### If you are using via some CI service, you can use following server specific variable.

### In Circle CI:
#REPOSITORY="${CIRCLE_PROJECT_USERNAME}/${CIRCLE_PROJECT_REPONAME}"

### In Travis CI:
#REPOSITORY="${TRAVIS_REPO_SLUG}"

### Determine release tag name
TAG=

### If you are using via some CI service, you can use following server specific variable.

### In Circle CI:
#TAG="${CIRCLE_TAG}"

### In Travis CI:
#TAG="${TRAVIS_TAG}"
