Docker rm blocks concurrent runs

I want to run a lot of docker containers in foreground mode like docker run johndoe/example doSomething. I don’t want to waste disk space on exited containers, so I have to remove them. But it takes about 9 seconds to remove an exited container, so I should remove the container after the command execution. That’s […]

docker – in production – HA

how to run docker in production, with a active/active or active/standby HA system? are there any guides or best practices? i am thinking of 3 scenarios: 1) NFS – for two servers – wich are prepped with docker-machine and mounting a shared NFS to /var/lib/docker/ – so both docker nodes should see the same files.

Why is my docker CI image not reproducible / running everywhere

I have a Dockerfile for doing CI. It uses the contents of a third party tarball which in-turn includes parts of Java Runtime (yes its ugly). $ git clone xxx $ cd xxx $ docker build . During execution the Dockerfile on ONE host requires “…/jre/…/server/” and executed on ANOTHER host requires “…/jre/…/client/” from that […]

File copied by Docker seen as a directory

I’m trying to dockerize a Stardog 3.1.3 community edition server. The container fails to start because it sees a directory instead of a license file. For the record, I’m on Windows. These are the steps I’m following: Create a data container docker create -v /data/stardog:/data/stardog –name stardog_data busybox /bin/true Copy the local license key to […]

Can I make memory savings with docker by using a common image?

I am running an application that is made up of over eighty micro services, all running in separately composed containers. However they are all based upon the same saved container. This is seems to be eating memory as each container runs in it’s own memory space. Would I be able to make any significant memory […]

Each container must have different IAM roles. Since there will be potentially be N containers with N different IAM roles running […]

Persistence for an ASP.NET 5 Web API running in a Docker container

I have an ASP.NET 5 Web API running in a Docker container. It happily accepts web requests and can be deployed anywhere you can install Docker. Now I’d like to link my Web API container to a NoSQL backend container that also runs in a container. I considered MongoDB, but as far as I can […]
