Community Applications: The Ultra Proxy Guide.

Problems

Unraid plugins rely on GitHub. Specifically, it needs to access github.com and raw.githubusercontent.com to fetch data.

manually Install CA

download the plugin in your PC:

https://raw.githubusercontent.com/Squidly271/community.applications/master/plugins/community.applications.plg

name it CA.plg and upload to /boot/config/plugins/.

go to Plugin Tab and install from the local file. It should still fail when downloading community.applications-***.txz.
manually download from the URL and upload it to /boot/config/plugins/community.applications/. (The path can be found in the source of plg by searching <FILE tag).
go to Plugin Tab and install from the local file.

Use docker to setup proxy

Since the terminal of unraid do not support package manager (and the alternative nerdpack is also a plugin), we would like to use docker to setup trojan proxy.

set up docker mirrors:

# docker mirrors
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<- "EOF"
{
    "registry-mirrors" : [
        "https://[yourid].mirror.aliyuncs.com",
        "https://registry.docker-cn.com",
        "http://hub-mirror.c.163.com"
    ]
}
EOF

prepare the config.json for trojan and put it to /boot/trojan/config.json. The local_port must be 1086!

pull and start the prepared image in terminal:

docker pull ashawkey/trojan-privoxy-client

# the default proxy:
# socks5://127.0.0.1:1086
# http://127.0.0.1:1087
docker run -d --name tpc -v /boot/config/trojan:/etc/trojan -p 1086:1086 -p 1087:1087 ashawkey/trojan-privoxy-client

# for custom config path and port:
# docker run -d --name tpc -v $config_dir:/etc/trojan -p $socks5_port:1086 -p $http_port:1087 ashawkey/trojan-privoxy-client

you could see the docker running smoothly in the Docker Tab.

Turn on auto-restart of this container.

Configure proxy settings for CA

Apps Tab: use curl to fetch.

CA plugin provides an explicit proxy.cfg to set the curl proxy (The code is located here).

Create /flash/config/plugins/community.applications/proxy.cfg and put:
```
port=1087
tunnel=1
proxy=http://127.0.0.1
```

Install Plugin: use wget to fetch (The code can be found in /usr/local/sbin/plugin).

Add to /boot/config/go:

# emhttp
http_proxy="http://127.0.0.1:1087" https_proxy="http://127.0.0.1:1087" /usr/local/sbin/emhttp &

# terminal
echo "export http_proxy=\"http://127.0.0.1:1087\"" >> /root/.bash_profile 
echo "export https_proxy=\"http://127.0.0.1:1087\"" >> /root/.bash_profile

Reboot and you are free to load Apps and install Plugins!
