The Distributed Monolith term surely has a bad press. When you read through blogs and conference talks I’m sure you’d better build a “traditional” monolith rather Read more
Suppose you want to run scala repl or groovy shell or any other repl-like executable. You should download executable, unpack it, set PATH environmnt variable and now you could use it. Can it be simple? Yes, dockerize everything.
Checkout this project from github and build containers:
$ cd docker-with-fig
$ fig build
It could take several minutes, depends on your internet connection.
You could also build only some of available container, for example with scala and groovy:
$ fig build scala groovy
Available containers are:
Now you could start for example scala:
$ fig run scala

You could also run command on docker container with use of files from your current directory because it is mapped to /project directory on docker. Container starts with /project directory as current directory.
For example you have a simple file in your current dir:
$ cat simplePrint.scala
You could run command with this file:
$ fig -f PATH_TO_DOCKER_WITH_FIG_PROJECT/fig.yml run scala scala simplePrint.scala
First 'scala' in command means that you want to run scala container and 'scala simplePrint.scala' means that you want to execute this command on container.
It is simple, isn't it? All you need is docker and fig and you could use repl or run command with scala, groovy, cojure and any other which are currently supported...
