Node.js w/ Bower (DEPRECATED)
Testing javascript
You can use Node.js to test some javascript (in interactive mode):
$ docker run -it --rm helder/node
> [0, 1, 2, 3].slice(0, 2);
[ 0, 1 ]
Bower
Add this alias to your profile:
alias bower='docker run -it --rm -v "$PWD:/data" helder/node gosu node bower'
Now you can just use bower from the current directory:
bower install jquery
UID mapping
By default, the node user's uid and gid will be set to the owner of the current working directory. If you wish to disable this feature, set the environment variable MAP_NODE_UID=no.
$ # run command as node user
$ docker run -it --rm helder/node gosu node id
uid=999(node) gid=999(node) groups=999(node)
$ # see that it is mapping
$ docker run -it --rm -v $PWD:/usr/src/app -w /usr/src/app helder/node gosu node id
uid=1000(node) gid=1000(node) groups=1000(node)
$ # use another directory
$ docker run -it --rm -v $PWD:/data -e MAP_NODE_UID=/data helder/node gosu node id
uid=1000(node) gid=1000(node) groups=1000(node)
$ # disable mapping
$ docker run -it --rm -v $PWD:/usr/src/app -w /usr/src/app -e MAP_NODE_UID=no helder/node gosu node id
uid=999(node) gid=999(node) groups=999(node)
With this mapping, assuming the current working directory is a host volume, now any files generated inside the container (e.g., with gulp or bower), should have the same uid and gid as your host's user.
