* Add support for setting alias when creatign instance.
The POST to create a instance now provides an `alias` field which
then can be used to access the instance services through the following
URL:
`http://<alias>-<short_session>-<port>.<tld>`
When creating a session you can now send an `alias`
* Remove unnecessary function
* Add alias support for DNS resolution
* Add DNS support for PWD instances
* Store IP address of PWD in all session networks and restore it with the
same IP address
* Remove unnecesary print
* Change url format to pwd<ip>-port for better DNS filtering
* Make PWD listen on 80 and 443 for DNS resolve to work
* - Enable use of override for session timeout. This is more useful than having to hard-code and rebuild the code for the previous 4 hour limit. Just set environmental variable and start the app.
- Future work may involve breaking down into minutes, but this is a good minimum delivery to provide value to end-user/developer.
- Fixes bug in Captcha code by introducing new landing page. This is not a new go template, it's a separate HTML file because SRP - single reponsibility principle. Happy for this to be refacted after merging commit.
- Fix for including Docker 1.12 override has been removed for later PR.
* Merge
* Reinstate 'material' JS include'
* https for JS includes
* HTTPs for JS in bypass
It works by using the Host of the request. When it receives something in
the form of: `<node>.<session>.play-with-docker.com` it does a reverse
proxy http request to `node`, validating that the `node` actually belongs
to the `session`.
If the node has a prefix `ip` and continues with a valid IP address
where the dots where replaces by underscores (like `ip10_0_0_1`) then it
will remove the `ip` prefix and and replace the underscores by dots, and
assume it is an ip address.
Add google recaptcha as an initial page before creating any session.
To configure recaptcha there are 2 environment variables that are needed
`GOOGLE_RECAPTCHA_SITE_KEY` and `GOOGLE_RECAPTCHA_SITE_SECRET`.
The code contains development defaults that should be set in production
to real values.
**NOTICE: Development defaults assume that the domain is `localhost`**
It fixes lots of bugs, can fallback to long polling, resize viewport of
terminals and share clients state of the session, so they all see the
same thing.
