犀牛 在犀类的后代中，现仅残存有犀牛科的4属5种，主要分布在亚洲和非洲，其中分布在亚洲的犀牛已经濒临绝种，非洲犀牛因为还有保护措施尚有族群。主要是因为犀牛角作为药材获利不菲，现行非洲犀牛角主要由养殖者所提供。南非养殖者会将犀牛角砍下，等待约一年半后再度收成，而部分盗猎者会将犀牛直接杀死取角，随盗猎导致数量减少，现在也不容易买到真正的犀牛角，现在商贩还懂得以牛羊的蛋白质部位替代来获利，甚至用相似成分的猫狗爪磨成假货变换充数。

Cleaning Up Stopped Containers
$ docker rm -v $(docker ps -aq -f status=exited)
> docker rm -v (docker ps -aq -f status=exited)
Accessing host machine from within docker container
Run docker container with option:
docker run --net=host ... or docker run --network host ...
Within the container to get the IP of the host:
route | awk '/^default/ { print $2 }' or ip route | awk '/^default/ { print $3 }'
stackoverflow.com - Let two Containers getting linked to eachother
Or
Add entries to container hosts file (–add-host):
docker run --add-host="docker:10.0.75.1"
Example:
docker run --add-host=docker:10.0.75.1 --rm -it byrnedo/alpine-curl -H "Accept: application/json" docker:8080/uaa/login
Accessing host machine from within docker container
Or
In docker-compose use network_mode: “host”
And alse need extra_hosts when you get error
extra_hosts:
- "moby:127.0.0.1"
extra_hosts
Add hostname mappings. Use the same values as the docker client--add-hostparameter.extra_hosts: - "somehost:162.242.195.82" - "otherhost:50.31.209.229"An entry with the ip address and hostname will be created in
/etc/hostsinside containers for this service, e.g:162.242.195.82 somehost 50.31.209.229 otherhost
Docker Machine – moby: Name or service not known
Container Proxy
docker run -e "http_proxy=http://myproxy.example.com:8080" \
-e "https_proxy=https://myproxy.example.com:8080" \
...
How to get a Docker container’s IP address from the host?
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container name or id>
docker inspect <container name or id> | grep "IPAddress"
How to get IP address when Docker containers in Hyper-V VM
如果你的 Windows 系统上的 Docker 默认使用 Hyper-V VM 实现，那么 Docker 命令参数 --net=host 就不是连的物理主机而是 Hyper-V VM 里的虚拟主机。想要查看此虚拟主机的 IP Address，首先通过 Windows 命令 ipconfig 查看发现 Ethernet adapter vEthernet (DockerNAT) 网络适配器的地址是如 10.0.75.1，那么再通过用 Advanced IP Scanner 软件扫描可以发现 10.0.75.2 地址，如果 Hyper-V VM 只有一个虚拟机，那么就是它了。
Configuration
Docker Daemon Proxy
- Create a systemd drop-in directory for the docker service:
$ sudo mkdir -p /etc/systemd/system/docker.service.d
- Create a file called
/etc/systemd/system/docker.service.d/http-proxy.confthat adds the HTTP_PROXY environment variable:
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/" "NO_PROXY=localhost,127.0.0.1"
or
$ cat <<EOF >/etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/" "NO_PROXY=localhost,127.0.0.1"
EOF
If you are behind an HTTPS proxy server
$ cat <<EOF >/etc/systemd/system/docker.service.d/https-proxy.conf
[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/" "NO_PROXY=localhost,127.0.0.1"
EOF
- Flush changes:
$ sudo systemctl daemon-reload
- Restart Docker:
$ sudo systemctl restart docker
- Verify that the configuration has been loaded:
$ systemctl show --property=Environment docker
Environment=HTTP_PROXY=http://proxy.example.com:80/

Issues
“New state of ‘nil’ is invalid”
Ah right, I get it now. Have verified just now that this is still an issue on docker master, but only when using the legacy (go-ansiterm emulated) console. Which means on any version of Windows before Windows 10, or Windows 10 with the console explicitly set to legacy mode. MC does run just fine on a Windows 10 client (with console in native/default mode) pointing to a Linux daemon:
Recommend: ConEmu with PowerShell on Windows
“New state of ‘nil’ is invalid” when attaching to container, probably related to UTF-8
