My projects

Docker images

Docker is a great tool supporting software development. Possibility to setup different software and networking configurations basing on one configuration file (docker-compose.yaml) greatly automates development tasks.

Dev2 – Dev. squared

It’s a set of Docker images developed to improve development work on LAMP applications.

The main goals are:

  • Eliminate password hassle and boring tasks (e.g. manual account creation)
  • Provide debugging out-of the box
  • Add network insight capabilities

One of the features of Dev2 is automatic uid:gid remapping. Usually uid of Linux desktop user is 1000, but containerized applications apply standards such as 33 for web servers.

Once when source files are shared with host, web server (web application) run in a container expects uid:gig: 33:33, but mounted files have 1000:1000.
To make development work smooth, Dev2 containers run file system that does a simple remapping of uid’s and gid’s, so developer can focus on essentials that is a Web app development. This filesystem is Dev2FS.

Dev2FS requires FUSE, thus Docker containers must run on elevated permissions.
To do so supplement ‘Docker run …’ with arguments:
–cap-add SYS_ADMIN –device /dev/fuse
or if you use docker-compose.yaml add: 

cap_add: ['SYS_ADMIN']
devices: 
  - /dev/fuse

Note that your host must have fuse module loaded: modprobe fuse

NOTE: Dev2 images has NOT been tested on other OS then Linux. Therefore at this point only this OS is supported.
