binenv

The last binary you'll ever install.

What

binenv will help you download, install and manage the binaries programs (a.k.a. distributions) you need in you everyday DevOps life (e.g. kubectl, helm, ...).

Think of it as a tfenv + tgenv + helmenv + ...

Quick start

Download a suitable binenv (yes, but wait !) for your architecture/OS at http://github.com/devops-works/binenv/releases.

Make it executable: chmod +x binenv.

Execute it: ./binenv update

Prepend ~/.binenv to your path in your ~/.bashrc or ~/.zshrc or ...: export PATH=~/.binenv:$PATH

While you're at it, install the completion: source <(binenv completion bash) (replace bash with your shell).

Now install binenv with binenv (so meta): binenv install binenv.

You can now remove the downloaded file: rm binenv.

Supported "distributions"

Distributions are installable binaries. We just had to find a name ¯\(ツ)/¯.

Currently supported distributions are:

• cli53
• consul
• kubectl
• helm
• terraform
• terragrun
• vault

The always up-to-date list is here.

Open an issue if you need one that is not in the list.

Usage

Updating available binaries

In order to update the list of installable version for distributions, you need to update the version list (usually located in $XDG_CONFIG/cache.json or ~/.config/binenv/cache.json).

This is done automatically when invoking binenv update.

Without arguments, il will check for available versions for all distributions (watch out for Github API rate limits).

With a distribution passed as an argument (e.g. binenv update kubectl), it will only update installable versions for kubectl.

Examples

• binenv update: update versions available for all distributions
• binenv update kubectl helm: update versions available for kubectl and helm

Installing new versions

After updating the list, you might want to install a shiny new version. No problem,binenv install has you covered.

If you want the latest non-prerelease version for something, just run:

binenv install something

If you want a specific version:

binenv install something 1.2.3

Note that completion works, so don't be afraid to use it.

You can also install serveral distribution versions at the same time:

binenv install something 1.2.3 somethingelse 4.5.6

Examples

• binenv install kubectl: install latest non-prerelease kubectl version
• binenv install kubectl 1.18.8: install kubectl version 1.18.8
• binenv install kubectl 1.18.8 helm 3.3.0: install kubectl version 1.18.8 and helm 3.3.0

Listing versions

You can list available, installed and activated distribution versions using binenv versions.

When invoked without arguments, all version of all distributions will be printed.

With distributions as arguments, only versions for those distributions will be printed.

In the output, versions having a * next to them are the currenly selected versions (see Selecting versions below.

Versions having a + next to them are installed.

All other versions are available to be installed.

Examples

$ binenv versions
kubectl:
        ...
        1.19.0-alpha.3
        1.19.0-alpha.2
        1.18.8* (from default)
        1.18.6
        1.18.5
        1.18.4
        1.18.3
        1.18.2
        1.17.11
        1.17.9+
        1.17.8
        1.17.8-rc.1
        1.17.7
        1.17.6
        1.17.5+
        1.16.14
        1.16.13
        1.16.12
        1.16.12-rc.1

terraform:
        0.13.0
        0.13.0-rc1
        0.13.0-beta3
...

Uninstalling versions

If you need to clean up a bit, you can uninstall a specific version, or all versions for a distribution. In the latter case, a confirmation will be asked.

The command accepts:

• a single argument (remove all versions for distributions)
• an even count of arguments (distribution / version pairs)

Examples

• binenv uninstall kubectl 1.18.8 helm 3.3.0: uninstall kubectl version 1.18.8 and helm 3.3.0
• binenv uninstall kubectl 1.18.8 kubectl 1.16.15: uninstall kubectl versions 1.18.8 and 1.16.15
• binenv uninstall kubectl: removes all kubectl versions

Update available distributions

Distributions are mainained in this repo. To benefit from new additions, you need to update the distribution list from time to time.

This list is usually located in your home directory under $XDG_CONFIG/distributions.yaml or ~/.config/binenv/distribution.yaml).

Usage is binenv distributions.

Completion

Install completion for your shell. See binenv help completion for in-depth info.

Selecting versions

To specify which version to use, you have to create a .binenv.lock file in the directory. Note that only semver is supported.

This file has the follosing structure:

<distributionA><constraintA>
<distributionB><constraintB>
...

For instance:

kubectl=1.18.8
terraform>0.12
terragrunt~>0.23.0

You can then commit the file in your project to ensure everyone in your team is on the same page.

The constraint operators are:

• =: version must match exactly
• !=: version must not match
• >: version must be strictly higher
• <: version must be strictly lower
• >=: version must be at least
• <=: version must be at most
• ~>: version must be at least this one in the same but match teh same minor versions

Version selection process

When you execute a distribution (e.g. you run kubectl), binenv runs it under the hood. Before running it, it will check which version it should use. For this, it will check for a .binenv.lock file in the curernt directory.

If none is found, it will check in the parent folder. No lock file ? Check in parent folder again. this process continues until binenv reaches your home directory.

If no version requirements are found at this point, binenv will use the last non-prerelease version available installed.

Removing binenv stuff

binenv stores downloadede binaries in ~/.binenv/binaries, and cache in ~/.config/binenv/ (or whatever your XDG_CONFIG variables points to).

To clean everything up:

rm -rf ~/.binenv ~/.config/binenv/

Status

This is really super alpha and has only be tested on Linux. YMMV on other platforms.

There are no tests. I will probably go to hell for this.
