# Distribution This section describes how to build and deploy publicly available releases of the Step CA. ## Creating A New Release New releases are (almost) entirely built and deployed by Travis-CI. Creating a new release is as simple as pushing a new github tag. **Definitions**: * **Standard Release**: ready for public use. no `-rc*` suffix on the version. e.g. `v1.0.2` * **Release Candidate**: not ready for public use, still testing. must have a `-rc*` suffix. e.g. `v1.0.2-rc` or `v1.0.2-rc.4` --- 1. **Tag it!** 1. Find the most recent tag. ``` $> git fetch --tags $> git tag ``` The new tag needs to be the logical successor of the most recent existing tag. See [versioning](#versioning) section for more information on version numbers. 2. Select the type and value of the next tag. Is the new release a *release candidate* or a *standard release*? 1. **Release Candidate** If the most recent tag is a standard release, say `v1.0.2`, then the version of the next release candidate should be `v1.0.3-rc.1`. If the most recent tag is a release candidate, say `v1.0.2-rc.3`, then the version of the next release candidate should be `v1.0.2-rc.4`. 2. Standard Release If the most recent tag is a standard release, say `v1.0.2`, then the version of the next standard release should be `v1.0.3`. If the most recent tag is a release candidate, say `v1.0.2-rc.3`, then the version of the next standard release should be `v1.0.3`. 3. Create a local tag. ``` # standard release $> git tag v1.0.3 ...or # release candidate $> git tag v1.0.3-rc.1 ``` 4. Push the new tag to the remote origin. ``` # standard release $> git push origin tag v1.0.3 ...or # release candidate $> git push origin tag v1.0.3-rc.1 ``` 2. **Check the build status at** [Travis-CI](https://travis-ci.com/smallstep/certificates/builds/). Travis will begin by verifying that there are no compilation or linting errors and then run the unit tests. Assuming all the checks have passed, Travis will build Darwin and Linux artifacts (for easily installing `step`) and upload them as part of the [Github Release](https://github.com/smallstep/certificates/releases). Travis will build and upload the following artifacts: * **step-ca_1.0.3_amd64.deb**: debian package for installation on linux. * **step-ca_linux_1.0.3_amd64.tar.gz**: tarball containing a statically compiled linux binary. * **step-ca_darwin_1.0.3_amd64.tar.gz**: tarball containing a statically compiled darwin binary. * **step-ca_1.0.3.tar.gz**: tarball containing a git archive of the full repo. 3. **Update the AUR Arch Linux package** > **NOTE**: if you plan to release `cli` next then you can skip this step.

    $ cd archlinux

    # Get up to date...
    $ git pull origin master
    $ make

    $ ./update --ca v1.0.3
    
4. **Update the Helm packages** > **NOTE**: This is an optional step, only necessary if we want to release a > new helm package. Once we have the docker images, we can release a new version in our Helm [repository](https://smallstep.github.io/helm-charts/) we need to pull the [helm-charts](https://github.com/smallstep/helm-charts) project, and change the following: * On step-certificates/Chart.yaml: * Increase the `version` number (Helm Chart version). * Set the `appVersion` to the step-certificates version. * On step-certificates/values.yaml: * Set the docker tag `image.tag` to the appropriate version. Then create the step-certificates package running:

    $ helm package ./step-certificates
    
A new file like `step-certificates-.tgz` will be created. Now commit and push your changes (don't commit the tarball) to the master branch of `smallstep/helm-charts` Next checkout the `gh-pages` branch. `git add` the new tar-ball and update the index.yaml using the `helm repo index` command:

    $ git checkout gh-pages
    $ git pull origin gh-pages
    $ git add "step-certificates-.tgz"
    $ helm repo index --merge index.yaml --url https://smallstep.github.io/helm-charts/ .
    $ git commit -a -m "Add package for step-certificates vX.Y.Z"
    $ git push origin gh-pages
    
***All Done!*** ## Versioning We use [SemVer](http://semver.org/) for versioning. See the [tags on this repository](https://github.com/smallstep/certificates) for all available versions.
