+# Release Uploader for Gitlab
+
+Creating releases on Gitlab seems to work only via the REST API.
+
+This Python script handles the upload of a release file, the creation of
+the required release tag in the repository and the creation of the actual
+release referring to both the tag and the file.
+
+It supports commandline options and an input file, adjusted to be used in
+Gitlab CI scripts.
+
+
+## Usage
+
+    wn@tron:~/workspace-python/gitlabreleaseuploader [master ≡]$ ./gitlabreleaseuploader.py -h
+    usage: gitlabreleaseuploader.py [-h] --privateToken PRIVATETOKEN --projectId

+### Without release info file:
+
+    gitlabreleaseuploader.py -p PRIVATE_TOKEN -i PROJECT_ID -u PROJECT_URL
+                             -f FILE_TO_BE_RELEASED -n RELEASE_NAME
+                             -t RELEASE_TAG -T RELEASE_TAG_TARGET -c
+                             -d RELEASE_DESCRIPTION -I INSTANCE_URL
+
+
+### With release info file:
+
+Release Info File:
+
+    {
+      "releaseTag": "v1.5",
+      "createReleaseTag": "true",
+      "releaseName": "Sixth release of the uploader",
+      "description": "Now with CI script and automatic release upload (hey, eat your own dogfood)"
+    }
+
+Command:
+
+    gitlabreleaseuploader.py -p PRIVATE_TOKEN -i PROJECT_ID -u PROJECT_URL
+                             -f FILE_TO_BE_RELEASED -F RELEASE_INFO_FILE
+
+
+### Use in CI script
+
+The PRIVATE_TOKEN should not be entered directly into the CI script but added as protected a CI variable to you particular project.
+
+Then add the following stage into your CI script:
+
+    release:
+            stage: release
+            image: registry.gitlab.com/wolutator/base-build-env
+            only:
+                    - release
+            script:
+                    - gitlabreleaseuploader.py -p $PRIVATE_TOKEN -i $CI_PROJECT_ID -u $CI_PROJECT_URL
+                      -f gitlabreleaseuploader.py -F info.json -T $CI_COMMIT_REF_NAME
+
+Note, please: this stage definition is for a docker worker. It uses my ``base-build-env`` image, which already contains the 
+uploader script. However, it is no problem to use the uploader script also in different environments. It just depends on the 
+``Requests`` package.
+
+Note too, please: this job is releasing the ``gitlabreleaseuploader.py`` script itself, so you see the name of the script twice in the CI script. Don't be confused, the option ``-f`` gets the file to be released.
+
+Most information are taken from CI builtin variables, the tag name, release name and release description should be stored in
+the release info file (here: ``info.json``), which is under version control.
+
+To avoid releasing a file with everything single push to an arbitrary branch, add the ``only`` block.
