bgadrian / docker.datadirectory
Created Nov 23, 2019
Docker change the data directory (Images, containers) on Ubuntu
View docker.datadirectory
According to the official documentation, as of Feb 2019, there are no --graph, -g options. These were renamed to the single argument --data-root.
vim /lib/systemd/system/docker.service so that the ExecStart takes into consideration that argument
ExecStart=/usr/bin/dockerd --data-root /mnt/data/docker -H fd://
systemctl daemon-reload
service docker restart

Hugo lazy image loading
View hugo_lazy_img.md

I presume the images are bundled as post resources in the ./images/ folder.

It creates a new version at 5% of its original quality that is fetched in the initial page load. When and if the original image is loaded by the browser it will replace the low quality one.

{{< lazyimg "images/1.jpeg" >}} {{< lazyimg "images/1.jpeg" "caption" >}}
