Docker Version Manager

Build Status

Version management for your Docker clients. Heavily influenced by nvm (ok, "borrowed" from). This tool modifies your current PATH to switch between different Docker clients.

dvm-usage

Escape from this error for a little bit longer:

Error response from daemon: client and server don't have same version (client : 1.18, server: 1.16)

Prerequisites

Mac OS X and Linux require curl or wget.

Installation

  1. Run the one of the installation scripts below.
  2. Copy, paste and run the commands from the installation output to finalize the installation.

Mac OS X and Linux

$ curl -sL https://download.getcarina.com/dvm/latest/install.sh | sh

Windows

Open a PowerShell command prompt and execute the following command. We use PowerShell 4 to do the initial installation but you can use dvm with PowerShell or CMD once it's installed.

Upgrading from previous dvm

If you have dvm 0.2 or later, run dvm upgrade to install the latest version of dvm.

If you have dvm 0.0.0, then you will need to reinstall. dvm used to only be only one shell script, relying on a git backed ~/.dvm. This worked well for *nix users and was not workable for Windows users. We've since switched over to small wrapper scripts and a go binary called dvm-helper to make cross platform simple and easy. To upgrade, you can either pull and rebuild yourself (with a working go setup), or use the install script. You'll need to open up a new terminal to ensure that all the dvm functions are set properly.

Usage

To install the 1.8.2 release of docker, do this:

dvm install 1.8.2

Now in any new shell use the installed version:

dvm use 1.8.2

If you want to see what versions are installed:

dvm ls

If you want to see what versions are available to install:

dvm ls-remote

To restore your PATH, you can deactivate it:

dvm deactivate

Bash and zsh completion

There is bash and zsh completion available in $DVM_DIR/bash_completion. To invoke it into your shell, run

[[ -r $DVM_DIR/bash_completion ]] && . $DVM_DIR/bash_completion

For zsh, there's a bit of special sauce using bashcompinit from the more recent versions of zsh.

Usage

$ dvm [TAB]
alias        install      ls           uninstall    which
current      list         ls-alias     unload
deactivate   list-alias   ls-remote    use
help         list-remote  unalias      version
$ dvm u[TAB]
unalias    uninstall  unload     use
$ dvm us[TAB]
$ dvm use [TAB]
