NB! You can specify many images to operate on, e.g:
lstags nginx~/^1\\.13/ mesosphere/chronos alpine~/^3\\./
Why would someone use this?
You could use
lstags, if you ...
- ... aggregate images from different external registries into your own registry for speed and locality reasons.
- ... compare images present locally with the registry ones (e.g.: know if image tagged "latest" was re-pushed).
- ... continuously pull Docker images from some public or private registry to speed-up Docker run on your system.
... pull Ubuntu 14.04 & 16.04, all the Alpine images and Debian "stretch" to have the latest software to play with:
lstags --pull ubuntu~/^1\\.04$/ alpine debian~/stretch/
... pull and re-push CoreOS-related images from
quay.io to your own registry (in case these hipsters will break everything):
lstags -P /quay -r registry.company.io quay.io/coreos/hyperkube quay.io/coreos/flannel
NB! In case you use private registry with authentication, make sure your Docker client knows how to authenticate against it!
lstags will reuse credentials saved by Docker client in its
config.json file, one usually found at
Possible image states
lstags distinguishes five states of Docker image:
ABSENT- present in registry, but absent locally
PRESENT- present in registry, present locally, with local and remote digests being equal
CHANGED- present in registry, present locally, but with different local and remote digests
LOCAL_ONLY- present locally, absent in registry
NOT_FOUND- absent in registry, absent locally, probably does not exist at all
You can either:
- rely on
lstagsdiscovering credentials "automagically" :tophat:
- load credentials from any Docker JSON config file specified
Sometimes registry may contain tags not exposed to any kind of search though still existing.
lstags is unable to discover these tags, but if you need to pull or push them, you may "assume"
they exist and make
lstags blindly try to pull these tags from the registry. To inject assumed
tags into the registry query you need to extend repository specification with a
= followed by a
comma-separated list of tags you want to assume.
e.g. we assume tags
v1.7.0 exist like this:
Full repository specification looks like this:
You may provide infinite number of repository specifications to
When you [re]push images to your "push" registry, you can control the destination repository path prefix:
- by default, repository path prefix will be auto-generated from the source registry hostname, e.g.:
--push-prefix=/will push images "as is", with no additional repository path prefix
--push-prefix=/my/prefix/will push images appending
/my/prefix/to the repository path
/my/prefixwithout trailing slash is OK, as long as path would still be formatted correctly by API :sparkles:
--push-prefix=""would trigger "default" behavior with prefix being auto-generated
To fail or not to fail?
By default application exits after encountering any errors. To make it more tolerant to subsequent failures, you may use CLI option
-N, --do-not-fail or set environment variable
DO_NOT_FAIL=true before running application. HINT: Option
-d, --daemon-mode always implies activation of
:bulb: You can load repositories from the YAML file just like you do it from the command line arguments:
lstags -f file.yaml
A valid YAML file looks like this (mandatory
lstags root key is here to be able to use "shared" YAMLs):
lstags: repositories: - busybox - nginx:stable - mesosphere/marathon-lb~/^v1/ - quay.io/coreos/awscli=master,latest,edge - gcr.io/google-containers/hyperkube~/^v1\.(9|10)\./
lstags can load repositories from YAML or from CLI args, but not from both at the same time!

A special wrapper script will be installed to manage
lstags invocation and updates. :sunglasses:
Install: From source

You are very welcome to open pull requests to this repository! :wink:
:warning: CI build will fail, if your commit messages are not semantic!
To maximize our collaboration efficiency we would humbly ask you to follow these recommendations:
- Please add reasonable description (what?/why?/etc) to your pull request :exclamation:
- Your code should pass CI (CircleCI) and a [pretty liberal] code review :mag:
- If code adds or changes some logic, it should be covered by a unit test :neckbeard:
- Please, put meaningful and semantic messages on your commits :pray:
NB! Not a requirement, but a GIF included in PR description would make our world a happier place!
'NORELEASE' branches and commits
We have automatic release system. Every PR merge will create a new application release with a changelog generated from PR branch commits. For the most cases it is OK. However, if you work with things that do not need to be released (e.g. non user-facing changes), you have following options:
- If you don't want to create release from your PR, make it from branch containing "NORELEASE" keyword in its name.
- If you want to prevent single commit from appearing in a changelog, please start commit message with "NORELEASE".
:warning: We don't build RPMs/DEBs/etc, as we see no need for it. We ship
lstags as a single binary or as a Docker container.
You may use lstags either as a standalone CLI or as a Golang package inside your own application.
Set up and build PoC application with our
make poc-app APP_PATH=../lstags-api cd ../lstags-api go build # run "./lstags-api" binary to see PoC in action (examine main.go first to ensure no "rm -rf /" is there)
- This installs all necessary dependencies and sets up PoC application at the path
- We assume you already have recent Golang version installed on your system https://golang.org/dl/
NB! Far more complete API usage example could be found in main.go :wink:
