Docker

Building Containers

• Build without working with cached data.

#!/bin/bash
docker build -t localphp:`date +%m%d%Y` -f Dockerfile --no-cache .
docker build -t localphp -f Dockerfile .

Networking

IP Forwarding

This is required to allow the containers to route out of the local docker network.

echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.conf
systemctl restart network

SELinux

Quick and dirty fix for mounting local volumes

chcon -Rt svirt_sandbox_file_t /directory/to/be/mounted

Or even better, just use the 'z' flag for mounting volumes.
