Re: [Resin-interest] "Rewriting" hostnames across webapps?
Yep, I think it would. The problem is, what if I want a more complex transformation next time? Or just a different string other than "stage" inserted? It's okay, this works well enough for me now.

Re: [Resin-interest] "Rewriting" hostnames across webapps?
Wouldn't adding "(stage\.)?" to each host-alias-regexp and changing the host-name to regexp allow it to work as you want it? For example: ^tycho.(stage\.)?latencyzero.com[\.]?$ ^(www\.)?(stage\.)?latencyzero.com[\.]?$ On Fri, Jan 17, 2014 at 3:18 PM, Rick Mann wrote: > > On Jan 17, 2014, at 06:05 , Paul Cowan wrote: > > > > > On Jan 16, 2014, at 4:32 PM, Rick Mann wrote: > > > >> I'm trying to update a virtual server that runs a handful of webapps in > Resin.

Basically, I have entries in resin.xml on machine "tycho.latencyzero.com" like this: ^tycho.latencyzero.com[\.]?$ ^(www\.)?latencyzero.com[\.]?$ comics.roderickmann.org ^(www\.)?roderickmann.org[\.]?$ ^(www\.)?rickmann.org[\.]?$ ^mgfb\.roderickmann.org[\.]?$ ^blog\.roderickmann.org[\.]?$ I have DNS entries for all of the above that are all CNAMEs to tycho.latencyzero.com. I want to move all of those apps to a new machine (upgrading hardware and OS), but I want to test it first. The machine is called stage.latencyzero.com, and I need to make new DNS entries for each webapp (perhaps adding "stage" to each name, or something). The most straightforward thing would be simply to modify each name to add "stage" to them, but then when I decide to make the new machine permanent, and change all the old DNS entries to point to the new IP address, I'd have to modify the entries. Or I could simply add host-aliases for all the new names. But I was hoping there'd be a trick so that I only have to modify one line, and each of the host entries would pick it up. I realize that might require me to modify all the entries once (as you did with your redirects). But once I do this once, it should work for similar changes in the future. One thing I need to preserve: if I'm hitting one of my webapps through the new name (e.g. "stage.mgfb.roderickmann.org" or whatever), when code in the webapp uses the host name to render URIs, it needs to use that same hostname, so that links point to the right place, and not back to the old instance. All this discussion, of course, has taken longer than it would have to simply modify the entries a couple times, but I was curious.

Hi Rick, I'm not exactly understanding what you want to do, but it sounds like I a similar situation I had on one of my sites. This configuration below is what I used. The new real host is listed first in resin.xml, then the default host id="" with host-alias * will catch all, and the redirect regex will redirect to the new site while appending the requested URI. .*foo.com … * http://www.foo.com$1"/> https://www.foo.com$1";> Hope this helps, -Paul > > Is there another technique to make this kind of migration easier? > > I did manually edit resin.xml for one of my webapps to respond to > "comics.stage.roderickmann.org," and created a DNS entry to match.
