Proxy configuration by command line for some tools

proxy-config.md

Yarn configuration

$ yarn config set proxy http://username:password@host:port

$ yarn config set https-proxy http://username:password@host:port

NPM configuration

$ npm config set proxy http://username:password@host:port

$ npm config set https-proxy http://username:password@host:port

Or you can edit directly your ~/.npmrc file:

proxy=http://username:password@host:port

https-proxy=http://username:password@host:port

https_proxy=http://username:password@host:port

Remove configuration

npm config rm proxy

npm config rm https-proxy

Git configuration

git config --global http.proxy http://username:password@host:port

git config --global https.proxy http://username:password@host:port

Or you can edit directly your ~/.gitconfig file:

[http]
        proxy = http://username:password@host:port
[https]
        proxy = http://username:password@host:port

Bower configuration

Edit your ~/.bowerrc file:

{
    "proxy":"http://username:password@host:port",
    "https-proxy":"http://username:password@host:port"
}

Maven configuration

Edit the proxies session in your ~/.m2/settings.xml file

<proxies>
    <proxy>
        <id>id</id>
        <active>true</active>
        <protocol>http</protocol>
        <username>username</username>
        <password>password</password>
        <host>host</host>
        <port>port</port>
        <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
</proxies>

Maven Wrapper

Create a new file .mvn/jvm.config inside the project folder and set the properties accordingly:

-Dhttp.proxyHost=host 
-Dhttp.proxyPort=port 
-Dhttps.proxyHost=host 
-Dhttps.proxyPort=port 
-Dhttp.proxyUser=username 
-Dhttp.proxyPassword=password

Docker

Native Docker

Depending on your OS, you have to edit a specific file (/etc/sysconfig/docker or /etc/default/docker).

Then, restart the docker service with: sudo service docker restart.

It will not apply to systemd. See this page: https://docs.docker.com/config/daemon/systemd/#httphttps-proxy

Docker with docker-machine

You can create your docker-machine with:

docker-machine create -d virtualbox \
    --engine-env HTTP_PROXY=http://username:password@host:port \
    --engine-env HTTPS_PROXY=http://username:password@host:port \
    default

Or you can edit the file ~/.docker/machine/machines/default/config.json.

Ubuntu

System-wide proxies in CLI Ubuntu/Server must be set as environment variables.

1. Open the /etc/environment file with vi (or your favorite editor). This file stores the system-wide variables initialized upon boot.

Add the following lines, modifying appropriately. You must duplicate in both upper-case and lower-case because (unfortunately) some programs only look for one or the other:

http_proxy="http://myproxy.server.com:8080/"
https_proxy="http://myproxy.server.com:8080/"
ftp_proxy="http://myproxy.server.com:8080/"
no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
HTTP_PROXY="http://myproxy.server.com:8080/"
HTTPS_PROXY="http://myproxy.server.com:8080/"
FTP_PROXY="http://myproxy.server.com:8080/"
NO_PROXY="localhost,127.0.0.1,localaddress,.localdomain.com"

2. apt-get, aptitude, etc. will not obey the environment variables when used normally with sudo. So separately configure them; create a file called 95proxies in /etc/apt/apt.conf.d/, and include the following:

Acquire::http::proxy "http://myproxy.server.com:8080/";
Acquire::ftp::proxy "ftp://myproxy.server.com:8080/";
Acquire::https::proxy "https://myproxy.server.com:8080/";

3. Verify that apt has picked up these settings via this command

apt-config dump | grep -i proxy # lists the proxy settings

Finally, logout and reboot to make sure the changes take effect.
