New print-css.rocks release available
A new print-css.rocks release is available with support for some new tools: Typeset.sh
Since two months I have been very busy with finding a working combination of Linux kernel, hardware and Linux distribution that would actually stable for running Docker in production. Only one out of eight combination worked for me.
Feel the pain and frustration?
All tests done with Docker 1.5.0 final without special configuration of the underlaying driver (AUFS vs. device mapper).
|Ubuntu 14.04||3.13||Bare metal||Hosteurope||the only working combination (using AUFS)||WORKING|
|Ubuntu 14.04||3.13||VM||Hosteurope||hoster-patched kernel in order to fit its OpenVZ virtualization||FAIL|
|OpenSuse 13.1||2.6||Bare metal||self-hosted||kernel panics after some minutes during a Docker build||FAIL|
|OpenSuse 13.1||3.11||Bare metal||self-hosted||kernel panics once or twice a day during Docker builds (possibly related to BTRFS crashes)||FAIL|
|CentOS 6.6||2.6||VM||Hetzner||slow IO, long Docker builds (10 times slower than on the same VM), likely related
to CentOS and/or the Docker device mapper (although supported by Docker)
|CentOS 7.0||>3.10||VM||Hetzner||slow IO, long Docker builds (10 times slower than on the same VM), likely related
to CentOS and/or the Docker device mapper (although supported by Docker). Also: Docker did not play well with the 'firewalld' of CentOS. Reconfiguration of the firewalld caused a network loss of all Docker containers and the docker daemon had to be restart....a major fail.
|Ubuntu 14.04||3.13||VM||Contabo||Docker builds much slower than directly on the same VM, not as extreme as with CentOS, Docker container execution speed OK||partly WORKING|
|CentOS 7.0||3.13||VM||Contabo||same problems as with other CentOS versions||FAIL|
However there is hope...the upcoming CoreOS Rocket runtime engine looks very promising...however Rocket is still in early stages. At least Rocket already supports loading Docker images. On the other side: Rocket tried to place a pull request for Docker in order to achieve image compatibility between Docker and Rocket ...but typically for the ignorance and arrogance of the Docker devs: they give a shit and only care about their own thing. Unfortunately the Docker developers are corrupted by too much venture captial and became ignorant through the Docker hype.
