Docker Hub 镜像加速器

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

Dockerized 实践 https://github.com/y0ngb1n/dockerized

1️⃣ Docker daemon 配置代理（推荐）

• 欧版 Bootloader 可以直接解锁，美版里V版不行，需要找奸商解锁。
• 其实只要 1）解锁 Bootloader，2）按照 ex. 刷入 modemst，就可以完成电信破解（已测试 Android 8.1）。
• 暂时不清楚 modemst 是否是各版本通用的。

1. 解锁 Bootloader

如果你在单个生产节点上用过Docker，然后发现单个节点的资源不够用，那么你会怎么做呢？我也遇到过这种情况! 关于在生产环境中使用Docker Swarm，我会为你提供一些建议，也许能够帮到你。这些都是我一年来积累的一些经验。

另外，如果你对Docker Swam不熟悉的话，可以参考我之前的博客My experience with Docker Swarm - when you may need it?（http://suo.im/1m7qW8）

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:

Guide:

1. Install Armbian_5.24.161216_Orangepizero_Ubuntu_xenial_3.4.113.img onto a uSD card using Win32DiskImager or Ubuntu Disk Image Writer

2. (Optional) Mount the uSD in Ubuntu Laptop and expand the partition using GParted.

3. Delete everything from uSD except /boot, /lib/modules and /lib/firmware.

4. Mount openwrt-15.05.1-sunxi-root.ext4 on Ubuntu using loopback interface on /mnt/openwrt

Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

• TCP port 2377 for cluster management & raft sync communications
• TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
• UDP port 4789 for "data plane" VXLAN overlay network traffic
• IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option
