rake not working

[LiNk-NY]

I'm trying to build and push the devel_core image to my docker hub but rake isn't working for me. I have used docker login and edited my auth.yml file. This is the error I'm getting:

> rake devel_core
running task devel_base...
rake aborted!
LoadError: cannot load such file -- docker
/home/user/Documents/github/bioc_docker/Rakefile:26:in `setup_docker'
/home/user/Documents/github/bioc_docker/Rakefile:66:in `block (3 levels) in <top (required)>'
Tasks: TOP => devel_core => devel_base
(See full trace by running task with --trace)

rake, version 10.5.0 Docker version 1.12.5, build 7392c3b

Thanks, MR

Install the docker ruby library:

gem install docker

Thanks for the response.

I'm getting this error now:

NoMethodError: undefined method `url=' for Docker:Module
/home/user/Documents/github/bioc_docker/Rakefile:33:in `setup_docker'
/home/user/Documents/github/bioc_docker/Rakefile:66:in `block (3 levels) in <top (required)>'
Tasks: TOP => devel_core => devel_base
(See full trace by running task with --trace)

Seems like the docker gem hasn't been tested with Ubuntu 16.04? (missing url method) Thanks Dan!

Sorry, I gave you the wrong command. Uninstall the docker package:

gem uninstall docker

And either install docker-api as follows:

gem install docker-api

or do the recommended thing which I should have said first, which is to install bundler:

gem install bundler # you can skip this if `which bundler` returns something

Then:

bundle install

Will install the dependencies in the Gemfile.

I ran into a snag with json 1.8.1 but I used bundle update and it's working now with json 2.0.2. Thanks again!
