binenv

One binary to rule them all. Manage all those pesky binaries (kubectl, helm, terraform, ...) easily.

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 + ...

Now you can install your favorite utility just by typing binenv install something.

Quick start

Linux (bash/zsh)

wget -q https://github.com/devops-works/binenv/releases/latest/download/binenv_linux_amd64 -O binenv
chmod +x binenv
./binenv update
./binenv install binenv
rm binenv
if [[ -n $BASH ]]; then ZESHELL=bash; fi
if [[ -n $ZSH_NAME ]]; then ZESHELL=zsh; fi
echo $ZESHELL
echo 'export PATH=~/.binenv:$PATH' >> ~/.${ZESHELL}rc
echo "source <(binenv completion ${ZESHELL})" >> ~/.${ZESHELL}rc
exec $SHELL

MacOS (with bash)

wget -q https://github.com/devops-works/binenv/releases/latest/download/binenv_darwin_amd64 -O binenv
chmod +x binenv
./binenv update
./binenv install binenv
rm binenv
echo 'export PATH=~/.binenv:$PATH' >> ~/.bashrc
echo 'source <(binenv completion bash)' >> ~/.bashrc
exec $SHELL

Windows

binenv does not support windows.

Install

wget -q https://github.com/devops-works/binenv/releases/latest/download/binenv-<OS>-<ARCH>
  • rename it
mv binaryname binenv
  • make it executable
chmod +x binenv
  • execute an update
./binenv update
  • now install binenv with binenv (so meta)
./binenv install binenv <version>
  • you can now remove the downloaded file
rm binenv
  • prepend ~/.binenv to your path in your ~/.bashrc or ~/.zshrc or ...
export PATH=~/.binenv:$PATH
  • while you're at it, install the completion (replace bash with your shell)
source <(binenv completion bash)
  • "restart" your shell
exec $SHELL

Updating binenv

Just run binenv install binenv

This is the whole point.

Usage

Updating available distributions versions

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, it will fetch the cache from this repo. This cache is
generated automatically daily.

Using the -f argument, binenv will retrieve available versions for all
distributions (watch out for Github API rate limits, but see
below
).

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

Note that Github enforces rate limits (e.g. 60 unauthenticated API requests per
hours). So you should update all distributions (e.g. binenv update -f) with
caution. binenv will stop updating distributions when you only have 4
unauthenticated API requests left.

GitHub tokens are also supported to avoid
being rate-limited and fetch releases from their respective sources.

Updating versions using a token

To avoid being rate limited, you can also use a personal access token.

To use the token, just export it in the GITHUB_TOKEN environment variable:

export GITHUB_TOKEN=aaa...bbb

Update available distributions

Distributions are maintained in this
file.

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 (often ~/.config/binenv/distribution.yaml).

To update only distributions:

binenv update --distributions # or -d

To update distributions and their versions:

binenv update --all # or -a

Examples

  • binenv update: update available versions for all distributions from github
    cache
  • binenv update -f: update available versions for all distributions from all
    releases
  • binenv update -d: update available distributions
  • binenv update kubectl helm: update available versions for kubectl and
    helm

Searching distributions

The search command lets you search a distribution by name or description:

$ binenv search kube
binenv: One binary to rule them all. Manage all those pesky binaries (kubectl, helm, terraform, ...) easily.
helm: The Kubernetes Package Manager
helmfile: Deploy Kubernetes Helm Charts
k9s: Kubernetes CLI To Manage Your Clusters In Style!
ketall: Like `kubectl get all`, but get really all resources
... (lots of things with "kube" in it)

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 several distribution versions at the same time:

binenv install something 1.2.3 somethingelse 4.5.6

Using the --dry-run flag (a.k.a -n) will show what would be installed.

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 printed in reverse mode are the currently selected
(a.k.a. active) versions (see Selecting versions below.

Versions in bold are installed.

All other versions are available to be installed.

Examples

$ binenv versions
terraform: 0.13.1 (/home/you/some/dir) 0.13.0 0.13.0-rc1 0.13.0-beta3 0.13.0-beta2 0.13.0-beta1 0.12.29 0.12.28 0.12.27 0.12.26 0.12.25 0.12.24 0.12.23 0.12.22 0.12.21 0.12.20 0.12.19 0.12.18 0.12.17 0.12.16 0.12.15 0.12.14 0.12.13 0.12.12 0.12.11 0.12.10 0.12.9 0.12.8 0.12.7 0.12.6
terragrunt: 0.23.38 0.23.37 0.23.36 0.23.35 0.23.34 0.23.33 0.23.32 0.23.31 0.23.30 0.23.29 0.23.28 0.23.27 0.23.26 0.23.25 0.23.24 0.23.23 0.23.22 0.23.21 0.23.20 0.23.19 0.23.18 0.23.17 0.23.16 0.23.15 0.23.14 0.23.13 0.23.12 0.23.11 0.23.10 0.23.9
toji: 0.2.4 (default) 0.2.2
vault: 1.5.3 1.5.2 1.5.1 1.5.0 1.5.0-rc 1.4.6 1.4.5 1.4.4 1.4.3 1.4.2 1.4.1 1.4.0 1.4.0-rc1 1.4.0-beta1 1.3.10 1.3.9 1.3.8 1.3.7 1.3.6 1.3.5 1.3.4 1.3.3 1.3.2 1.3.1 1.3.0 1.3.0-beta1 1.2.7 1.2.6 1.2.5 1.2.4
...

(the output above does not show bold or reverse terminal output)

Freezing versions

When the versions command is invoked with the --freeze option, it will
write a .binenv.lock style file on stdout.

This way you can "lock" the dependencies for your project just by issuing:

cd myproject
binenv versions --freeze > .binenv.lock

You can the commit this file to your project so everyone will use the same
distributions versions when in this repository. See Selecting Versions for more information on this file.

Note that currently selected versions for all distributions will be
outputted. You might want to trim stuff you do not use from the file.

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

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 following 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 the 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 current 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 installed.

Install versions form .binenv.lock

Install versions specified in .binenv.lock file, you can use the --lock
(a.k.a. -l) flag.

Example

$ cat .binenv.lock
terraform>0.13.0
helmfile<0.125.0
hadolint<1.17.0
$ binenv install -l
2020-08-29T11:39:18+02:00 WRN installing "terraform" (0.13.1) to satisfy constraint "terraform>0.13.0"

Removing binenv stuff

binenv stores downloaded binaries in ~/.binenv/binaries, and a cache in
~/.config/binenv/ (or whatever your XDG_CONFIG variable points to).

To wipe everything clean:

rm -rfi ~/.binenv ~/.config/binenv/

Don't forget to remove the PATH and the completion you might have changed in
your shell rc file.

Status

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

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

FAQ

I installed a binary but is still see the system (or wrong) version

Try to rehash your binaries (hash -r in bash or rehash in Zsh).

After installing a distribution, I get a "shim: no such file or directory"

If you see something like:

2020-11-10T09:01:20+01:00 ERR unable to install "kubectl" (1.19.3) error="unable to find shim file: stat /Users/foo/.binenv/shim: no such file or directory"

you probably did not follow the installation instructions.

Running ./binenv update binenv && ./binenv install binenv should correct the
problem.

I don't like binenv, are there alternatives ?

Sorry to hear that. Don't hesitate opening an issue or sending a PR is
something does not fit your use case

Some nice alternatives exist:

The distributions.yaml file used by default by binenv is located here, don't hesitate to have a look on it's structure.

Caveats

Since binenv uses your PATH and HOME to find binaries and layout it's
configuration files, using sudo with binenv-installed binaries is not very
straightforward. You can either install binenv as the root user (so it can find
it's config), or pass those two environment variables when invoking sudo, like
so:

sudo env "PATH=$PATH" "HOME=$HOME" binary_installed_with_binenv ...
