Issue #, if available:

closes #93
closes #83
closes #76
closes #57

as mentioned in the above issues, VERSION is fixed at 1.2.0.0 causing the session-manager-plugin to exit after 30 seconds. (ref: #83 (comment)) This behavior makes the plugin unusable when using it as a library from other tools.

Additionally, the README does not mention the need to edit the VERSION, which results in non-functional binaries when built from the source code. In fact, a non-working version is bundled with Alpine.

$ docker run --rm -it alpine
/ # apk add aws-session-manager-plugin
