Deploying to new canister on mainnet

Developers
1

I have currently deployed a canister to mainnet. Is there a way to deploy a second canister with the same code base to mainnet and just choose which one I want to deploy to ad-hoc?

Check out this thread: Deploy an app twice on the IC (Staging env)

I see, so if I specify --network staging, it will deploy to a different canister than if I specify --network ic?

Yep, as long as you configure it the way I demonstrate there

dfx deploy --network staging gives and error:

The replica returned an HTTP Error: Http Error: status 404 Not Found, content type "text/html", content: <html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.21.3</center>
</body>
</html>

I saw this error on the other thread as well. Was this ever resolved?

Ah, it’s failing because you don’t have a wallet configured for “staging”.

Run this:

dfx identity --network staging set-wallet $(dfx identity --network ic get-wallet)

I’ll add a note to the Readme

Hmm, I’m still getting

Creating UI canister on the staging network.

@kpeacock Do you know what might be causing the error? ^

Maybe it’s trying to install the Candid UI canister? This didn’t happen when I ran it, so I’m not sure. Try specifying your canister short name with

dfx deploy --network staging <canister-name>

and definitely verify that the wallet is set up for staging correctly with

dfx identity --network staging get-wallet

It seems to keep trying to install the UI canister, even with dfx deploy --network staging . Is there a way to disable this?

Specify the name of the canister in the command. It will only deploy the specific canister

It seemed to deploy correctly (I see the canister id when i go to .raw.ic0.app/, but I tried to change the code and deploy changes with dfx deploy --network staging <canister name>, but it still returns the same error:

<hr><center>nginx/1.21.3</center>

</html>

even when specifying deploying a particular name

@kpeacock Sorry for bothering you again, but do you know what might be going wrong ^? I’m pretty sure my dfx.json and whatnot is the same as the github you shared
