docker-crash-course's Issues

02-todo-web-application-h2 Fail

For this project I have completed the following steps using Intellij 20 IDE three times: one time each on two different Ubuntu OS machines and one time on a Windows 10 OS machine, resulting in the same problem:

• Run SpringBootFirstWebApplication

• Go to http://localhost8080/login in Chrome - receive the login page

• Entered the login credentials: in28minutes/dummy; click the Sign in button

• All three instances return:
  This localhost page can't be found
  No webpage was found for the web address: http://locahost:8080/

   HTTP ERROR 404
  

Have I missed something? Is there something additional that needs to be downloaded and installed to make this run without issues?

Thank you for your time.

Upgrade dockerfile-maven-plugin

See https://search.maven.org/artifact/com.spotify/dockerfile-maven-plugin

Connection refused: no further information executing GET http://localhost:8000/currency-exchange/from/EUR/to/INR

For this proyect 06-currency-conversion-service I am presenting an error when I run it as it is, as Java Application. tried downloading the codes again. resulting in the same problem:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

Tue Mar 30 18:49:27 CLST 2021
There was an unexpected error (type=Internal Server Error, status=500).
Connection refused: no further information executing GET http://localhost:8000/currency-exchange/from/EUR/to/INR
feign.RetryableException: Connection refused: no further information executing GET http://localhost:8000/currency-exchange/from/EUR/to/INR

Remove all repository entries from your example project pom files

In more or less all of your project you defined repositories like this:

	<repositories>
		<repository>
			<id>spring-snapshots</id>
			<name>Spring Snapshots</name>
			<url>https://repo.spring.io/snapshot</url>
			<snapshots>
				<enabled>true</enabled>
			</snapshots>
		</repository>
		<repository>
			<id>spring-milestones</id>
			<name>Spring Milestones</name>
			<url>https://repo.spring.io/milestone</url>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</repository>
	</repositories>

	<pluginRepositories>
		<pluginRepository>
			<id>spring-snapshots</id>
			<name>Spring Snapshots</name>
			<url>https://repo.spring.io/snapshot</url>
			<snapshots>
				<enabled>true</enabled>
			</snapshots>
		</pluginRepository>
		<pluginRepository>
			<id>spring-milestones</id>
			<name>Spring Milestones</name>
			<url>https://repo.spring.io/milestone</url>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</pluginRepository>
	</pluginRepositories>

If you are not using milestone versions there are not needed cause the GA releases of Spring boot are available via Central repository.

Upgrade Spring Boot versions

https://search.maven.org/artifact/org.springframework.boot/spring-boot

2.2.5.RELEASE for example.
