[RESOLVED] Having issues getting coder_apps to appear in my Workspace

Hello, I have been familiarizing myself with Coder the past few days, and it is fantastic. I just have one thing that I'm getting pretty stuck on and I'm hoping that I can get some help. I am using the guacamole terraform provider by techBeck03, and it creates a guacamole connection that I can connect to at https://guac.example.com/#/client/abcxyz. I am trying to get that URL as a clickable link on my Coder Workspace, but I can't seem to figure out how to get it to appear. It seems logical that I could create a coder_app resource with the url set to the desired URL and external=true. While building the template doesn't give me issues, it doesn't actually display it anywhere. This is the primary reference material I am looking at: https://coder.com/docs/v2/latest/ides/web-ides I believe that the major disconnect is coming from how my resource is displayed in the Workspace, as I'm not using (what appears to be Kubernetes) in my workspace, I am using libvirt via dmacvicar's libvirt terraform provider. EDIT: It turns out that functionality of ALL coder_app's is dependent on the coder-agent being present on the terraform resources VMs, containers, etc. This apparently includes external apps.

Can you share the template?

bamhm182 (BytePen)•10mo ago

Discord won't let me send it as one message, so I'm going to have to split it across a few...

terraform {
  required_providers {
    coder = { source = "coder/coder" }
    libvirt = { source = "dmacvicar/libvirt" }
    guacamole = { source = "techBeck03/guacamole"}
  }
}

provider "libvirt" {}
provider "coder" {}
provider "guacamole" {}

data "coder_workspace" "me" {}

resource "coder_metadata" "deployment" {
  resource_id = "coder-${data.coder_workspace.me.owner}-${data.coder_workspace.me.name}"
  item {
    key = "Guacamole URL"
    value = format("%s%s", "https://guacamole.example.com/#/client/", base64encode(format("%s%s%s%s%s", guacamole_connection_rdp.rdp.identifier, base64decode("AA=="), "c", base64decode("AA=="), "postgresql")))
  }
}

resource "coder_agent" "main" {
  os   = "linux"
  arch = "amd64"
}

resource "coder_app" "guacamole" {
  agent_id = coder_agent.main.id
  slug = "guacamole"
  display_name = "Guacamole"
  url = "https://guacamole.example.com/#/"
  external = true
}

resource "libvirt_domain" "domain" {
  name = "coder-${data.coder_workspace.me.owner}-${data.coder_workspace.me.name}"
  ...snip...
  }
}

data "guacamole_connection_group" "group" {
  path = data.coder_workspace.me.owner
}

resource "guacamole_connection_rdp" "rdp" {
  name = data.coder_workspace.me.name
  parent_identifier = data.guacamole_connection_group.group.identifier
  ...snip...
}

terraform {
  required_providers {
    coder = { source = "coder/coder" }
    libvirt = { source = "dmacvicar/libvirt" }
    guacamole = { source = "techBeck03/guacamole"}
  }
}

provider "libvirt" {}
provider "coder" {}
provider "guacamole" {}

data "coder_workspace" "me" {}

resource "coder_metadata" "deployment" {
  resource_id = "coder-${data.coder_workspace.me.owner}-${data.coder_workspace.me.name}"
  item {
    key = "Guacamole URL"
    value = format("%s%s", "https://guacamole.example.com/#/client/", base64encode(format("%s%s%s%s%s", guacamole_connection_rdp.rdp.identifier, base64decode("AA=="), "c", base64decode("AA=="), "postgresql")))
  }
}

resource "coder_agent" "main" {
  os   = "linux"
  arch = "amd64"
}

resource "coder_app" "guacamole" {
  agent_id = coder_agent.main.id
  slug = "guacamole"
  display_name = "Guacamole"
  url = "https://guacamole.example.com/#/"
  external = true
}

resource "libvirt_domain" "domain" {
  name = "coder-${data.coder_workspace.me.owner}-${data.coder_workspace.me.name}"
  ...snip...
  }
}

data "guacamole_connection_group" "group" {
  path = data.coder_workspace.me.owner
}

resource "guacamole_connection_rdp" "rdp" {
  name = data.coder_workspace.me.name
  parent_identifier = data.guacamole_connection_group.group.identifier
  ...snip...
}

...snip... ...snip... In the above example, I would like resource.coder_app.guacamole to appear anywhere on the workspace, and it seems like it would appear near the resource.coder_agent.main, but it doesn't appear anywhere. I was looking at it again, and there were quite a few irrelevant lines in there. I condensed it down to show a more direct example.

If you open https://guacamole.example.com/#/" in your browser can you accesss the rdp desktop?

bamhm182 (BytePen)•10mo ago

Not quite, but it would achieve the same functionality. That url is just a url. It doesn't matter if it's guacamole, Google, whatever, just trying to get a button with a link to appear. The garbage up in coder_metadata.deployment is the actual code that generates the actual URL needed to drop right into RDP. It works as a stop gap because I can just click that metadata item to copy it, open a new tab, and paste it in the address bar.

hey @bamhm182 (BytePen) you could post the template as a file otherwise i'm looking into your issue on my end, it seems that there's no issue with your template

bamhm182 (BytePen)•10mo ago

I have a bunch of stuff that isn't relevant. I will get a simple example together and upload a file with screenshots.

Phorcys•10mo ago

yeah, the only relevant part should be

resource "coder_app" "guacamole" {
  agent_id = coder_agent.main.id
  slug = "guacamole"
  display_name = "Guacamole"
  url = "https://guacamole.example.com/#/"
  external = true
}

resource "coder_app" "guacamole" {
  agent_id = coder_agent.main.id
  slug = "guacamole"
  display_name = "Guacamole"
  url = "https://guacamole.example.com/#/"
  external = true
}

it's just that having the entire template is almost always better to help not missing out on stuff :-)

bamhm182 (BytePen)•10mo ago

For sure. I appreciate it. I'm going to generate a template with digital ocean, since that should be easy to wholly recreate on your end.

Phorcys•10mo ago

honestly don't bother, it should definitely show up with any provider do you have multiple coder_agents declared by any chance ?

bamhm182 (BytePen)•10mo ago

Yeah, that's why I figured I'd create a simple one that you'd be able to replicate without having to have a libvirt host.

Phorcys•10mo ago

what coder version are you running ?

bamhm182 (BytePen)•10mo ago

terraform.tf

bamhm182 (BytePen)•10mo ago

v2.4.0+d19a762 I just have a single coder_agent I bailed on creating a new DO template and just uploaded the libvirt one I'm using. Then I had the idea to modify my existing one to include the exact same discord coder_app (copy-pasted) that I have in my libvirt template. For some reason it works there... Actually, I'm having some issues with DO as well... Let me track down some issues that may or may not be related and follow up in a minute.

Phorcys•10mo ago

hey, I do get the guacamole app to show up when using the exact same app definition
