I can’t quite wrap my head around the documentation and the examples to figure out what I need.  
I have a repo that contains golang and node\_js code. I want to run two stages that

1. tests/builds the go code
2. tests/builds the js code  
and then the output of both those builds should run in an `after_success` step to build a single docker image with the compiled files.

* * *

I’ve tried with the `matrix` but am getting two docker images built:

```auto
services:
  - docker

matrix:
  include:
    - language: go
      go:
        - "1.11"
      script:
        - make test
        - make build

    - language: node_js
      node_js:
        - "7"
      script: yarn run build

after_success:
  - docker build

```

What does this configuration give you, and how does it fall short of your expectations?

The problem is that the `js` build takes a little bit longer to execute, but the `after_success` executes before `yarn run build` is complete, and the files generated are not in the docker image.

My expectation is that `after_success` only runs once, after all jobs are complete and successful.

If you want these two jobs to be in different stages (and guarantee sequential execution), you need to define different `stage` values. This is explained in [https://docs.travis-ci.com/user/build-stages/](https://docs.travis-ci.com/user/build-stages/).

</div>

The ordering of the jobs doesn’t matter, they just have to all run before `after_success`

But, since running them sequentially isn’t a hard requirement at this point, using stages would be ok with me. However the documentation of stages (or any examples I found) does not show me how to use multiple languages. Can you take my example and convert it to use stages?

I think I was overlooking a critical element of your question.

Jobs are run independently within a build. One job does not have any clue as to what the rest are doing. So,

This is not possible.

I suggest combining the builds into a single job. Use `nvm` to manage Node.js versions if necessary.

ok, that was something I looked into for a workaround already.  
What I wanted to do was use a go image as a base, then install node on it, and then use that to build the jobs, but using a custom image seemed like a lot more overhead to do this.

so…can you give me an example of running these two languages in one job?
