anyone know how i can avoid resource replacement in case of changing the provider? i just want to apply to provider without doing anything else
l
I've always done this by manually editing the state. It may be possible via aliases, but I doubt it.
b
ive manual too, but its alot of them this time 🥵
aliases will not help
l
It's usually a straight-forward search and replace, I think?
b
i got huge stack with many changes, imma mess it up for sure
in the past just setting 
--target
to something random used to just ignore provider changes, for some reason it doesnt work for me this time
l
Definitely back your stack up! 🙂
b
manual is not an option for me here
l
Why not?
b
its too many changes in too many places, those places are also very sensitive
l
The number shouldn't matter. Search and replace. So long as you have a backup, it won't be a problem. You're not going to push any changes to your provider, all changes will be state-only. If you see a change that would go out to the cloud, then you don't make that change.
You can even sort-of test by importing your exported stack to a new stack, and work there. That's probably not worth it though, since you need to make code and stack changes in parallel, to prevent anything being pushed to the cloud.

im going to use both 
pulumi preview --json
and 
pulumi stack export
to automate it

heres the script:
Copy code
const { stdout } = await runProcess({
  command: 'pulumi',
  commandArgs: ['stack', 'export'],
});
const state = JSON.parse(stdout.toString());
const resources: any[] = [];
const { stdout } = await runProcess({
  command: 'pulumi',
  commandArgs: ['preview', '--json'],
});
const diff = JSON.parse(stdout.toString());
const providerReplaces: { urn: string; newProvider: string }[] = [];
for (const step of diff.steps) {
  if (step.op === 'replace' && step.replaceReasons.includes('provider')) {
    providerReplaces.push({ urn: step.urn, newProvider: step.newState.provider });
  }
}
for (const resource of state.deployment.resources) {
  const replacement = providerReplaces.find((r) => r.urn === resource.urn);
  if (replacement) {
    resource.provider = replacement.newProvider;
  }
  resources.push(resource);
}
state.deployment.resources = resources;
console.log(JSON.stringify(state));
