Archive	Create automated and user-invocable scripts that archive and extract selected files/directories with optional compression (gzip or zstd).	../../../../.icons/folder.svg	false	backup archive tar helper

Archive

This module installs small, robust scripts in your workspace to create and extract tar archives from a list of files and directories. It supports optional compression (gzip or zstd). The create command prints only the resulting archive path to stdout; operational logs go to stderr. An optional stop hook can also create an archive automatically when the workspace stops, and an optional start hook can wait for an archive on-disk and extract it on start.

module "archive" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/coder-labs/archive/coder"
  version  = "0.0.1"
  agent_id = coder_agent.main.id

  paths = ["./projects", "./code"]
}

Features

• Installs two commands into the workspace $PATH: coder-archive-create and coder-archive-extract.
• Creates a single .tar, .tar.gz, or .tar.zst containing selected paths (depends on tar).
• Optional compression: gzip, zstd (depends on gzip or zstd).
• Stores defaults so commands can be run without arguments (supports overriding via CLI flags).
• Logs and status messages go to stderr, the create command prints only the final archive path to stdout.
• Optional:
  • create_on_stop to create an archive automatically when the workspace stops.
  • extract_on_start to wait for an archive to appear and extract it on start.

Warning

The create_on_stop feature uses the coder_script run_on_stop which may not work as expected on certain templates without additional provider configuration. The agent may be terminated before the script completes. See coder/coder#6174 for provider-specific workarounds and coder/coder#6175 for tracking a fix.

Usage

Basic example:

module "archive" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/coder-labs/archive/coder"
  version  = "0.0.1"
  agent_id = coder_agent.main.id

  # Paths to include in the archive (files or directories).
  directory = "~"
  paths = [
    "./projects",
    "./code",
  ]
}

Customize compression and output:

module "archive" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/coder-labs/archive/coder"
  version  = "0.0.1"
  agent_id = coder_agent.main.id

  directory    = "/"
  paths        = ["/etc", "/home"]
  compression  = "zstd"        # "gzip" | "zstd" | "none"
  output_dir   = "/tmp/backup" # defaults to /tmp
  archive_name = "my-backup"   # base name (extension is inferred from compression)
}

Enable auto-archive on stop:

module "archive" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/coder-labs/archive/coder"
  version  = "0.0.1"
  agent_id = coder_agent.main.id

  # Creates /tmp/coder-archive.tar.gz of the users home directory (defaults).
  create_on_stop = true
}

Extract on start:

module "archive" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/coder-labs/archive/coder"
  version  = "0.0.1"
  agent_id = coder_agent.main.id

  # Where to look for the archive file to extract:
  output_dir   = "/tmp"
  archive_name = "my-archive"
  compression  = "gzip"

  # Waits up to 5 minutes for /tmp/my-archive.tar.gz to be present, note that
  # using a long timeout will delay every workspace start by this much until the
  # archive is present.
  extract_on_start             = true
  extract_wait_timeout_seconds = 300
}

Command usage

The installer writes the following files:

• $CODER_SCRIPT_DATA_DIR/archive-lib.sh
• $CODER_SCRIPT_BIN_DIR/coder-archive-create
• $CODER_SCRIPT_BIN_DIR/coder-archive-extract

Create usage:

coder-archive-create [OPTIONS] [PATHS...]
  -c, --compression <gzip|zstd|none>   Compression algorithm (default from module)
  -C, --directory <DIRECTORY>          Change to directory for archiving (default from module)
  -f, --file <ARCHIVE>                 Output archive file (default from module)
  -h, --help                           Show help

Extract usage:

coder-archive-extract [OPTIONS]
  -c, --compression <gzip|zstd|none>   Compression algorithm (default from module)
  -C, --directory <DIRECTORY>          Extract into directory (default from module)
  -f, --file <ARCHIVE>                 Archive file to extract (default from module)
  -h, --help                           Show help

Examples:

• Use Terraform defaults:

  coder-archive-create
  

• Override compression and output file at runtime:

  coder-archive-create --compression zstd --file /tmp/backups/archive.tar.zst
  

• Add extra paths on the fly (in addition to the Terraform defaults):

  coder-archive-create /etc/hosts
  

• Extract an archive into a directory:

  coder-archive-extract --file /tmp/backups/archive.tar.gz --directory /tmp/restore
