Introduction#

If you’re working with Azure, you might have encountered an error that looks something like this:

“Failure sending request: StatusCode=0 — Original Error: Code=‘ReferencedResourceNotProvisioned’ Message=‘Cannot proceed with operation because resource used by resource is not in Succeeded state. Resource is in Updating state and the last operation that updated/is updating the resource is PutSubnetOperation.’”

Though the error message can seem intimidating and cryptic at first, don’t worry. In this post, we’ll delve into what this error means and how you can resolve it.

The example below will import an AWS instance into a terraform module:

terraform import module.foo.aws_instance.bar i-abcd1234

In the realm of Infrastructure as Code, Terraform modules can play a significant role in making your life easier. Sometimes, however, these modules don’t live at the root directory of their source package. Instead, they reside in sub-directories. Thankfully, Terraform has a smart way to help you access these nested modules.

Terraform employs a unique double-slash (//) syntax to help pinpoint the exact sub-directory where the module is located. The path that follows this double-slash syntax is considered to be a sub-directory within the package or repository.

Understanding the Issue: ‘RPC failed; HTTP 413 curl 22’#

If you’ve stumbled upon the error message “RPC failed; HTTP 413 curl 22 The requested URL returned error: 413 Request Entity Too Large,” you’re probably trying to push a rather hefty commit over HTTP to your server running Nginx. This error means that the size of the request you’re trying to send exceeds the limit that the server is willing to accept. So, how do you fix it?

Install the gems on the destination machine from the local files:

cd /path/to/gems
gem install --force --local *.gem

Are you stuck with two Git repositories or branches that have completely different histories, but you need to merge them? You may be hitting a roadblock because Git is designed to prevent this kind of operation by default. However, there’s a workaround for this, and it’s simpler than you might think.

The Problem: Unrelated Git Histories#

Imagine you’re working on a project where you have a main branch, and someone else has a completely separate project with its own history. Now, you want to combine both projects into a single repository. If you try to perform a regular git merge or git rebase, Git will likely stop you with an error message, something like:

Following one-liner will search for a ip address pattern in the specified file and replace it with the one provided :

sed 's/[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}/**IPADDRESS-COMES-HERE**/g' /SourceFilename > /DestinationFilename
