3 years ago Hi,
you made everything correct.
simplewebmatcher-1.0-web is the docker image name.
The error indicates, that you should also include the java docker dependencies in your evaluation project:
<dependency>
<groupId>com.github.docker-java</groupId>
<artifactId>docker-java-core</artifactId>
<version>3.2.7</version>
</dependency>
<dependency>
<groupId>com.github.docker-java</groupId>
<artifactId>docker-java-transport-httpclient5</artifactId>
<version>3.2.7</version>
</dependency>We excluded it initially, because we want to make the packages small when building a fat jar without requiring docker. Thus it is currently necessary to include the dependencies yourself. I will update the documentation.
Furthermore, if the docker image is already loaded in your local docker repository, then you can also use the constructor which only needs the image name: MatcherDockerFile(String imageName). Otherwise the image will be loaded everytime from the file into the local repository.
Please let me know if this solves your problem.
Best regards Sven

Describe the bug I follow the guideline on the
[page](https://dwslab.github.io/melt/matcher-packaging/web#evaluate-and-re-use-the-docker-file)to do MELT Web Package. When it comes to Evaluate and Re-Use a Web Interface Matcher in MELT，there are 2 blanks in the code exmaple I need to fill. What confuses me is the second one：MatcherDockerFile dockerMatcher = new MatcherDockerFile("<provide docker image name>", dockerFile);what's \<provide docker image name>？To Reproduce I have run
docker imagesin my PowerShell，the execution results are：So， I'm sure docker images contains simplewebmatcher-1.0-web, and the tag is latest.
I have tried the code
MatcherDockerFile dockerMatcher = new MatcherDockerFile("simplewebmatcher-1.0-web", dockerFile);, which means I use image name to fill the <provide docker image name>. The error massage is:Then I tried the code
MatcherDockerFile dockerMatcher = new MatcherDockerFile("simplewebmatcher-1.0-web:latest", dockerFile);, which means I use image name:Tag to fill the <provide docker image name>. The error massage is:Expected behavior So I want to know what's the \<provide docker image name> should be? Can you please give me an example? Thank u very much!!!
