I wouldn't advise growing silver lace vine anywhere in the PNW regardless of how dry it is where you live and whether or not you have it in a container or in the ground. You not only have to consider its invasive and tough, destructive vine habit if you don't keep it completely controlled and trimmed back
every week to 10 days, you also have to consider that nature has other ways of transporting the pollen and the seeds to places outside of your control. The stuff is as bad or even worse than the noxious kudzu in the south/east and the Himalayan Blackberry brambles that are now invading and strangling things all over the PNW and right up north all the way to the Alaska panhandle.
Plus there's always the possibility that a concerned neighbor might recognize it and report you. That's because it's being monitored in Washington state and people are supposed to report it to authorities if they see it growing. The silver lace vine isn't officially on the Washington Noxious Weed List
yet but it is headed that way and is presently listed as a Weed of Concern in Washington and is now listed on the Washington Noxious Weed
Monitor List - here is the monitor list:

I think if you want to grow some kind of vining and flowering plant with similar rapid growth habits that will do well in a container you should look for something that is definitely not invasive or that is an indigenous native to the PNW, not a foreign invasive that poses serious risk to the local environment, habitats and local agriculture.
If you look online there are several examples can be found of PNW native vines. The 6 following examples of native vines are from this website:
