migration

Really migrate this image into the inner intranet, without any internet connection.

Registry Changing

You have to comment the proxy definition, or your registry instance will restart frequently, thus your dind won’t get working using registry.

# vim /root/data/config.yml
	#proxy:
		# remoteurl: https://registry-1.docker.io
# docker restart docker-registry-proxy-2

systemd definition

Define following two systemd units:

# vim /etc/systemd/system/playwithdocker.service 
[Unit]
Description=playwithdocker
After=docker.service
Requires=docker.service

[Service]
Environment=GOPATH=/root/go/
ExecStart=/usr/bin/docker-compose -f /root/go/src/github.com/play-with-docker/play-with-docker/docker-compose.yml up -d

[Install]
WantedBy=multi-user.target

This unit will start blog service automatically.

# vim /etc/systemd/system/playwithdockerblog.service 
[Unit]
Description=playwithdockerblog
After=docker.service
Requires=docker.service

[Service]
ExecStart=/usr/bin/docker-compose -f /root/Code/play-with-docker.github.io/docker-compose.yml up -d

[Install]
WantedBy=multi-user.target
# systemctl enable playwithdocker.service
# systemctl enable playwithdockerblog.service

Next time the service will automatically start.

Offline CSS/js

bootstrap fonts:

# wget https://github.com/twbs/bootstrap/archive/v3.3.7.zip
# unzip bootstrap-3.3.7.zip
# cd fonts
# mkdir ~/Code/play-with-docker.github.io/_site/fonts/
# cp * ~/Code/play-with-docker.github.io/_site/fonts/

Then your image will display correctly.

Google Fonts

Download the Fonts description from the website, then put all of the related fonts under your local folder.

dnsmasq

Download the rpm package via:

# yum install yum-plugin-downloadonly
# yum reinstall --downloadonly --downloaddir=/root/rpms dnsmasq

Transfer the package to intranet and install it. Then edit the configuration file of dnsmasq:

# vim /etc/dnsmasq.conf
address=/192.192.189.114/192.192.189.114
# systemclt enable dnsmasq && systemctl start dnsmasq
