How to pass an array of arguments (ie. all/most starting with a dash)?

Terraform Providers

I’m trying to install Traefik using helm_release. However, to make TLS stuff work, i have to pass a bunch of command line parameters. Should i use helm to install this chart, my values.yaml would contain this:

additionalArguments:
  - --api.insecure=true\n- --accesslog=true
  - --certificatesresolvers.myresolver.acme.tlschallenge=true
  - --certificatesresolvers.myresolver.acme.email=my@address.here
  - --certificatesresolvers.myresolver.acme.storage=acme.json
  - --certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory

However, i can’t make this work with Terraform and helm_release. Here’s what i tried, and the error messages i got. In all cases i use this “template”:

set {
    name = "additionalArguments"
    value = xxx
}

With jsonencode:

jsonencode([
      "--api.insecure=true",
      "--accesslog=true",
      "--certificatesresolvers.myresolver.acme.tlschallenge=true",
      "--certificatesresolvers.myresolver.acme.email=my@address.here",
      "--certificatesresolvers.myresolver.acme.storage=acme.json",
      "--certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory"
    ])

│ Error: template: traefik/templates/daemonset.yaml:3:14: executing "traefik/templates/daemonset.yaml" at <.>: range can't iterate over ["--api.insecure=true"

With a stringified list (it might have been a bad idea anyway):

"--api.insecure=true,--accesslog=true,--certificatesresolvers.myresolver.acme.tlschallenge=true,--certificatesresolvers.myresolver.acme.email=my@address.here,--certificatesresolvers.myresolver.acme.storage=acme.json,--certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory"

│ Error: template: traefik/templates/daemonset.yaml:3:14: executing "traefik/templates/daemonset.yaml" at <.>: range can't iterate over --api.insecure=true

Same, without commas:

│ Error: template: traefik/templates/daemonset.yaml:3:14: executing "traefik/templates/daemonset.yaml" at <.>: range can't iterate over --api.insecure=true --accesslog=true --certificatesresolvers.myresolver.acme.tlschallenge=true --certificatesresolvers.myresolver.acme.email=my@address.here --certificatesresolvers.myresolver.acme.storage=acme.json --certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory

│ Error: template: traefik/templates/daemonset.yaml:3:14: executing "traefik/templates/daemonset.yaml" at <.>: range can't iterate over --api.insecure=true --accesslog=true --certificatesresolvers.myresolver.acme.tlschallenge=true --certificatesresolvers.myresolver.acme.email=my@address.here --certificatesresolvers.myresolver.acme.storage=acme.json --certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory

With an actual JSON string (i know it seems the same as the first example, but who knows…):

"[\"--api.insecure=true\",\"--accesslog=true\",\"--certificatesresolvers.myresolver.acme.tlschallenge=true\",\"--certificatesresolvers.myresolver.acme.email=my@address.here\",\"--certificatesresolvers.myresolver.acme.storage=acme.json\",\"--certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory\"]"

│ Error: template: traefik/templates/daemonset.yaml:3:14: executing "traefik/templates/daemonset.yaml" at <.>: range can't iterate over ["--api.insecure=true"

An actual array (i should have known this won’t work):

["--api.insecure=true","--accesslog=true","--certificatesresolvers.myresolver.acme.tlschallenge=true","--certificatesresolvers.myresolver.acme.email=my@address.here","--certificatesresolvers.myresolver.acme.storage=acme.json","--certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory"]

│ Inappropriate value for attribute "value": string required.

So the question is, how should i do it?
