Docker Desktop is not respecting proxy settings under Windows 10 Professional

SOLUTION:

• Option 1:configure Docker Desktop to use Manual proxy settings: the "whale" context menu / Settings / Resources / Proxies / Manual proxy configuration
• Option 2: (might work, didn't test) set HTTP_PROXY / HTTPS_PROXY / NO_PROXY as system environment variables, not user ones

In both cases, restart Docker Server

Original Problem:

To wire-print requests/responses over HTTP for SOAP/XML:

-Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true -Dcom.sun.xml.ws.transport.http.HttpAdapter.dump=true -Dcom.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump=true -Dcom.sun.xml.internal.ws.transport.http.HttpAdapter.dump=true -Dcom.sun.xml.internal.ws.transport.http.HttpAdapter.dumpTreshold=true

Snippet to quickly get Java system properties:

public class My {
  public static void main(String[] argc) {
 System.getProperties().stringPropertyNames().forEach(name -> System.out.println(name + "=" + System.getProperty(name)));

Thoughts on how to add trusted store for connection to external sites that use that certificate for HTTPS

Option 1: global configuration

One can just provide the -Djavax.net.ssl.trustStore=<path/to/store> -Djavax.net.ssl.trustStorePassword=<password> options when running the Java application

However, this is not always possible (for example, when run in the cloud).

And if you want to use server.ssl.trust-store/server.ssl.trust-store-password options from Spring Boot, be aware that with those you also have to provide key-store options as well. And, basically that would be an abuse, because this configuration is specifically for server side of your application.

How to debug an HTTPS connection issue with Spring Boot based Java application

1. Advanced logging:

• java -jar -Djavax.net.debug=ssl:handshake:verbose app.jar

2. make sure you specify correct configuration:

• java -jar -Djavax.net.debug=ssl:handshake:verbose app.jar --server.port=8443 --server.security.require-ssl=true --server.ssl.key-store=/path/to/keystore --server.ssl.key-store-password=password --server.ssl.protocol=TLS

3. See what’s in the store:

• keytool -list -keystore /path/to/keystore -storepass password

It's very annoying when you write some code at work, say, reproducible cases for OSS issues, but then commit those under work-related credentials and push on GH

To avoid this from happening, I've wrote such a pre-push hook and put it into .git-templates folder (see recipe on global hooks)

#!/bin/bash -e
#
# Git pre-push hook that blocks push if commits are authored or committed using non-personal credentials
#
# Source: https://github.com/git/git/blob/87c86dd14abe8db7d00b0df5661ef8cf147a72a3/templates/hooks--pre-push.sample

• Show table DDL:
  select dbms_metadata.get_ddl('TABLE', '<your table name>') from dual

• List all of the (available) tables: select * from user_tables
