Question 1

go-getter vs wget for downloading files in Go

Accepted Answer

go-getter is a Go library that provides a unified API for multiple protocols (Git, S3, etc.), ideal for embedding in tools like Terraform. wget is a command-line tool for HTTP/FTP, better suited for shell scripts. Use go-getter for complex, multi-source downloads in Go applications.

Question 2

how to use go-getter with private Git repositories

Accepted Answer

For private Git repos, use the sshkey query parameter to provide a base64-encoded SSH private key, or use SSH URLs like git::ssh://git@example.com/repo. Ensure Git 2.3+ is installed, as noted in the Git protocol options.

Question 3

go-getter checksum verification example

Accepted Answer

Append a checksum query parameter to the URL, e.g., ./file.txt?checksum=sha256:abc123 or using a file reference. go-getter verifies integrity after download and skips if the file exists with a matching checksum, as explained in the 'Checksumming' section.

Question 4

does go-getter support SSH for Git

Accepted Answer

Yes, go-getter supports SSH for Git through URLs like git::ssh://git@example.com/repo or scp-style addresses. SSH keys can be provided via the sshkey option, but this requires Git 2.3+ to work properly.

Question 5

go-getter security best practices

Accepted Answer

Enable security options like DisableSymlinks, set timeouts, and limit X-Terraform-Get redirects. Always sanitize return values to avoid logging sensitive data, as highlighted in the README's security warnings.

Question 6

how to disable unarchiving in go-getter

Accepted Answer

Set the archive query parameter to false in the URL, e.g., ./path?archive=false. This overrides the default automatic unarchiving based on file extensions, as described in the 'Unarchiving' section.

Question 7

go-getter S3 authentication setup

Accepted Answer

Provide AWS credentials via query parameters like aws_access_key_id and aws_access_key_secret, or use environment variables. For Minio, similar parameters are required with optional region settings, as detailed in the S3 protocol options.
