ACME (Let's Encrypt) with DNS challenge on platform.sh
NOTICE: Platform.sh launched builtin support for Let's Encrypt on April 20, 2017. So most likely you won't need this any more. Read more on Platform.sh's blog.
Platform.sh previously didn't support using ACME/Let's Encrypt certificates (at least not with domain verification and automatic renewal).
This Docker image provides scripting for obtaining certificates via ACME/Let's Encrypt and uploading them to Platform.sh using their API.
This Docker image is based on lego to obtain a certificate via ACME DNS challenge and uploads the certificate to platform.sh using their commmand line client.
Necessary configuration via environment variables, .i.e.:
ACME_EMAILemail@example.com(used for registering with Let's Encrypt)
DOMAINS="example.com www.example.com"(space separated list --
must already be added to the project at Platform.sh)
DNS_PROVIDER=dnsimple(your DNS provider, see below for supported
providers and additional needed configuration)
PLATFORMSH_API_TOKEN=mytoken(an APIv1 token)
You also need to provide environment variables required by the DNS provider challenge chosen:
Optional configuration via environment variables:
ACME_SERVER=https://acme-staging.api.letsencrypt.org/directory(optional ACME server -- defaults to Let's Encrypts production server)
ACME_DAYS=30(the number of days left on a certificate to renew it. Defaults to 30)
The container will store the certificates in
/data so you should mount a volume to
