Migrating Task Templates for Coder version 2.28.0

Warning

Starting June 2, 2026, Coder Tasks will move to a 12-month Extended Support Release (ESR) for Premium customers.

Tasks will be removed from new Coder releases beginning with v2.37 (September 1, 2026) and will only be available via the ESR during the support period.

We recommend transitioning to Coder Agents, the long-term replacement.

Prior to Coder version 2.28.0, the definition of a Coder task was different to the above. It required the following to be defined in the template:

1. A Coder parameter specifically named "AI Prompt",
2. A coder_workspace_app that runs the coder/agentapi binary,
3. A coder_ai_task resource in the template that sets sidebar_app.id. This was generally defined in Coder modules specific to AI Tasks.

Note that 2 and 3 were generally handled by the coder/agentapi Terraform module.

Important

The pre-2.28.0 definition is no longer supported as of Coder 2.30.0. You must update your Tasks-enabled templates to use the new format described below.

You can view an example migration here. Alternatively, follow the steps below:

Upgrade Steps

1. Update the Coder Terraform provider to at least version 2.13.0:

terraform {
  required_providers {
    coder = {
      source = "coder/coder"
-      version = "x.y.z"
+      version = ">= 2.13"
    }
  }
}

1. Define a coder_ai_task resource and coder_task data source in your template:

+data "coder_task" "me" {}
+resource "coder_ai_task" "task" {}

1. Update the version of the respective AI agent module (e.g. claude-code) to at least 4.0.0 and provide the prompt from data.coder_task.me.prompt instead of the "AI Prompt" parameter.

module "claude-code" {
  source              = "registry.coder.com/coder/claude-code/coder"
-  version             = "4.0.0"
+  version             = "4.0.0"
    ...
-  ai_prompt           = data.coder_parameter.ai_prompt.value
+  ai_prompt           = data.coder_task.me.prompt
}

1. Add the coder_ai_task resource and set app_id to the task_app_id output of the Claude module.

Note

Refer to the documentation for the specific module you are using for the exact name of the output.

resource "coder_ai_task" "task" {
+ app_id = module.claude-code.task_app_id
}

Coder Tasks format pre-2.28

Below is a minimal illustrative example of a Coder Tasks template pre-2.28.0. Note that this is NOT a full template.

terraform {
  required_providers {
    coder = {
      source = "coder/coder"
    }
  }
}

data "coder_workspace" "me" {}

resource "coder_agent" "main" { ... }

# The prompt is passed in via the specifically named "AI Prompt" parameter.
data "coder_parameter" "ai_prompt" {
  name    = "AI Prompt"
  mutable = true
}

# This coder_app is the interface to the Coder Task.
# This is assumed to be a running instance of coder/agentapi
resource "coder_app" "ai_agent" {
  ...
}

# Assuming that the below script runs `coder/agentapi` with the prompt
# defined in ARG_AI_PROMPT
resource "coder_script" "agentapi" {
  agent_id     = coder_agent.main.id
  run_on_start = true
  script       = <<EOT
    #!/usr/bin/env bash
    ARG_AI_PROMPT=${data.coder_parameter.ai_prompt.value} \
    /tmp/run_agentapi.sh
  EOT
  ...
}

# The coder_ai_task resource associates the task to the app.
resource "coder_ai_task" "task" {
  sidebar_app {
    id = coder_app.ai_agent.id
  }
}

Tasks format from 2.28 onwards

In v2.28 and above, the following changes were made:

• The explicitly named "AI Prompt" parameter is no longer supported. The task prompt is now available in the coder_ai_task resource (provider version 2.12 and above) and coder_task data source (provider version 2.13 and above).
• Modules no longer define the coder_ai_task resource. These must be defined explicitly in the template.
• The sidebar_app field of the coder_ai_task resource is now deprecated. In its place, use app_id.

Example (not a full template):

terraform {
  required_providers {
    coder = {
      source = "coder/coder"
      version = ">= 2.13.0"
    }
  }
}

data "coder_workspace" "me" {}

# The prompt is now available in the coder_task data source.
data "coder_task" "me" {}

resource "coder_agent" "main" { ... }

# This coder_app is the interface to the Coder Task.
# This is assumed to be a running instance of coder/agentapi (for instance, started via `coder_script`).
resource "coder_app" "ai_agent" {
  ...
}

# Assuming that the below script runs `coder/agentapi` with the prompt
# defined in ARG_AI_PROMPT
resource "coder_script" "agentapi" {
  agent_id     = coder_agent.main.id
  run_on_start = true
  script       = <<EOT
    #!/usr/bin/env bash
    ARG_AI_PROMPT=${data.coder_task.me.prompt} \
    /tmp/run_agentapi.sh
  EOT
  ...
}

# The coder_ai_task resource associates the task to the app.
resource "coder_ai_task" "task" {
  app_id = coder_app.ai_agent.id
}
