I’ve got 3 Node/Redis/Mongo stacks that I’m sending identical write streams to each. The architectural differences are: A: all hosted locally on OSX B: using standardized Docker images on boot2docker C: using the same Docker images on GCE (Google Compute Engine) Just focusing on Redis for a second, I get the following results under constant […]
I am running centos 6.5 minimal with the latest version of docker. I created a container from a centos 6.6 image and that is running fine. I then installed chef server 12 onto the container but when i run reconfigure it errors out: [2015-03-06T01:32:47+00:00] ERROR: Running exception handlers Running handlers complete [2015-03-06T01:32:47+00:00] ERROR: Exception handlers […]
I am following this article and have included my AWS credentials. I installed several CLI things required, and now get: $ ./trainer start 5 Greetings, cchilders/cchilders! The output of `ssh-add -l` doesn’t contain ‘RSA’. Start the agent, add your keys? I have already did eval $(ssh-agent) which doesn’t help.
I’m so confused. I created an EC2 Instance. So this isn’t a “Host”? It’s a container instance? I’m confused then if that’s the case. Then what’s the host for the images or how does this work? I pulled an image from docker hub to it, pushed the image to the AWS registry, and then now […]
I’m running community gerrit cookbook in docker using chef-solo. If I run the cookbook in a Dockerfile as a build step, it throws an error (check the log). But if I run the image and go inside the container and run the same command, it works fine. Any idea what’s going on? Its complaining about […]
I am building an image based on ubuntu14.04, try to enable ssh on the container. I am following the tutorial: https://docs.docker.com/examples/running_ssh_service/ But this tutorial only shows how to ssh using password, I want to use my own key to ssh into container instead of password. So I can do something like this in the vagrantfile […]

I’m using Elastic Beanstalk to deploy my application as a Single Docker Application. My Dockerfile does composer install while deploying, but I get a Could not authenticate against github.com error. I use these lines in my Dockerfile to install my dependencies: WORKDIR /www RUN [“composer”, “install”, “-o”] How would I solve this issue?
When running an Ubuntu Docker container on Mac or other OS host, is the UBunto OS really running in the container or is it some kind of a virtual interface? From my understanding containers share the OS, I just need to understand if it is the OS from the host or it really is a […]
