Juju provides for manual placement so that you can place a workload on an existing machine within an environment without provisioning a new machine.. ie juju deploy charm --to=existing_machine it also supports creating containers (either lxc or kvm) to run those workloads in isolation from the host (see juju deploy --help for more details). This is also supported for add-unit --to=existing_machine.
If you want to setup a single machine environment with a workload and the capacity to grow on virtual machines using manual provisioning in conjunction with manual placement makes this use case relatively straightforward. configure a 'null' aka manual environment in environments.yaml pointing to the ip address of the vm (don't use localhost but the ip address that other machines in the environment will use). Then juju bootstrap. Then juju deploy charm --to=0. cheers, Kapil On Thu, Jan 23, 2014 at 1:55 AM, Gandhi, Ibha (HP Software) <[email protected]>wrote: > Thanks John for the quick reply. > > -----Original Message----- > From: John Arbash Meinel [mailto:[email protected]] > Sent: Thursday, January 23, 2014 12:13 PM > To: Gandhi, Ibha (HP Software); Juju email list > Subject: Re: Juju on existing VM > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > On 2014-01-23 10:33, Gandhi, Ibha (HP Software) wrote: > > Hi, > > > > > > > > I want to deploy application on a specific VM and don?t want to > > provision a new VM. > > > > This is something I have been doing with chef, please let me know if > > it?s possible to deploy > > > > application on a particular VM through juju without provisioning a new > > one. > > > > > > > > Thanks, > > > > -Ibha > > We are currently polishing some work we call "manual provisioning" > where you have a machine, which you then add into an existing environment. > The syntax is something like: > juju add-machine ssh:user@host > > I believe that work isn't very polished in the latest stable release > (1.16.5) but is quite a bit better in our current unstable snapshot > (1.17.0) and should be polished for the next stable (1.18). > > John > =:-> > > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.13 (Cygwin) > Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ > > iEYEARECAAYFAlLgufsACgkQJdeBCYSNAANpEgCbBTV0vD7DXjzQCy4VWQqHVS37 > voMAn3uLE4lwV+9ZvmWpOCQw4BP3sbGv > =pb7H > -----END PGP SIGNATURE----- > > -- > Juju mailing list > [email protected] > Modify settings or unsubscribe at: > https://lists.ubuntu.com/mailman/listinfo/juju >
