Simple tool to create a list of docker tags from a given version string.
## Environment variables
```Shell
# if not set a comma-separated list will be printed to stdout
DOCKER_AUTOTAG_OUTPUT_FILE=
# adds a given suffix to every determined tag
DOCKER_AUTOTAG_SUFFIX=
# version string to use; returns 'latest' if nothing is specified
DOCKER_AUTOTAG_VERSION=
# comma-seprated list of static tags to add to the result set
DOCKER_AUTOTAG_EXTRA_TAGS=
# 'latest' tag would only be used if determined tag list is empty; adds always 'latest' to the result
DOCKER_AUTOTAG_FORCE_LATEST=False
# if the given version string contains a prerelease, no other tags will be returned
DOCKER_AUTOTAG_IGNORE_PRERELEASE=False
```
## Examples
```Shell
DOCKER_AUTOTAG_VERSION=1.0.1 docker-autotag
# 1.0.1,1.0,1
DOCKER_AUTOTAG_VERSION=0.1.0 docker-autotag
# 0.1.0, 0.1
## 'v' prefixes e.g. from git tags will be removed
DOCKER_AUTOTAG_VERSION=v1.0.1 docker-autotag
# 1.0.1,1.0,1
## unsufficient semver version strings will be tried to convert automatically
## if conversion doesn't work return 'latest'
DOCKER_AUTOTAG_VERSION=1.0 docker-autotag
# 1.0.0,1.0,1
DOCKER_AUTOTAG_VERSION=1.0.0-beta docker-autotag
# 1.0.0-beta
## ignore prerelease to always get a full list of tags
DOCKER_AUTOTAG_IGNORE_PRERELEASE=True DOCKER_AUTOTAG_VERSION=1.0.0-beta docker-autotag
# 1.0.0-beta,1.0.0,1.0,1
DOCKER_AUTOTAG_SUFFIX=amd64 DOCKER_AUTOTAG_VERSION=1.0.0 docker-autotag
# 1.0.0,1.0,1,1.0.0-amd64,1.0-amd64,1-amd64
DOCKER_AUTOTAG_EXTRA_TAGS=extra1,extra2 DOCKER_AUTOTAG_VERSION=1.0.0 docker-autotag
# 1.0.0,1.0,1,extra1,extra2
```
