deploy_challenge() {
local DOMAIN="${1}" TOKEN_FILENAME="${2}" TOKEN_VALUE="${3}"
# This hook is called once for every domain that needs to be
# validated, including any alternative names you may have listed.
#
# Parameters:
# - DOMAIN
# The domain name (CN or subject alternative name) being
# validated.
# - TOKEN_FILENAME
# The name of the file containing the token to be served for HTTP
# validation. Should be served by your web server as
# /.well-known/acme-challenge/${TOKEN_FILENAME}.
# - TOKEN_VALUE
# The token value that needs to be served for validation. For DNS
# validation, this is what you want to put in the _acme-challenge
# TXT record. For HTTP validation it is the value that is expected
# be found in the $TOKEN_FILENAME file.
# Simple example: Use nsupdate with local named
# printf 'server 127.0.0.1\nupdate add _acme-challenge.%s 300 IN TXT "%s"\nsend\n' "${DOMAIN}" "${TOKEN_VALUE}" | nsupdate -k /var/run/named/session.key
}
clean_challenge() {
local DOMAIN="${1}" TOKEN_FILENAME="${2}" TOKEN_VALUE="${3}"
# This hook is called after attempting to validate each domain,
# whether or not validation was successful. Here you can delete
# files or DNS records that are no longer needed.
#
# The parameters are the same as for deploy_challenge.
# Simple example: Use nsupdate with local named
# printf 'server 127.0.0.1\nupdate delete _acme-challenge.%s TXT "%s"\nsend\n' "${DOMAIN}" "${TOKEN_VALUE}" | nsupdate -k /var/run/named/session.key
}
deploy_cert() {
local DOMAIN="${1}" KEYFILE="${2}" CERTFILE="${3}" FULLCHAINFILE="${4}" CHAINFILE="${5}" TIMESTAMP="${6}"
# This hook is called once for each certificate that has been
# produced. Here you might, for instance, copy your new certificates
# to service-specific locations and reload the service.
#
# Parameters:
# - DOMAIN
# The primary domain name, i.e. the certificate common
# name (CN).
# - KEYFILE
# The path of the file containing the private key.
# - CERTFILE
# The path of the file containing the signed certificate.
# - FULLCHAINFILE
# The path of the file containing the full certificate chain.
# - CHAINFILE
# The path of the file containing the intermediate certificate(s).
# - TIMESTAMP
# Timestamp when the specified certificate was created.
# Simple example: Copy file to nginx config
# cp "${KEYFILE}" "${FULLCHAINFILE}" /etc/nginx/ssl/; chown -R nginx: /etc/nginx/ssl
# systemctl reload nginx
{% if docker_apache is defined %}
docker exec apache apache2ctl graceful

deploy_ocsp() {
local DOMAIN="${1}" OCSPFILE="${2}" TIMESTAMP="${3}"
# This hook is called once for each updated ocsp stapling file that has
# been produced. Here you might, for instance, copy your new ocsp stapling
# files to service-specific locations and reload the service.
#
# Parameters:
# - DOMAIN
# The primary domain name, i.e. the certificate common
# name (CN).
# - OCSPFILE
# The path of the ocsp stapling file
# - TIMESTAMP
# Timestamp when the specified ocsp stapling file was created.
# Simple example: Copy file to nginx config
# cp "${OCSPFILE}" /etc/nginx/ssl/; chown -R nginx: /etc/nginx/ssl
# systemctl reload nginx
}
unchanged_cert() {
local DOMAIN="${1}" KEYFILE="${2}" CERTFILE="${3}" FULLCHAINFILE="${4}" CHAINFILE="${5}"
# This hook is called once for each certificate that is still
# valid and therefore wasn't reissued.
#
# Parameters:
# - DOMAIN
# The primary domain name, i.e. the certificate common
# name (CN).
# - KEYFILE
# The path of the file containing the private key.
# - CERTFILE
# The path of the file containing the signed certificate.
# - FULLCHAINFILE
# The path of the file containing the full certificate chain.
# - CHAINFILE
# The path of the file containing the intermediate certificate(s).
}
invalid_challenge() {
local DOMAIN="${1}" RESPONSE="${2}"
# This hook is called if the challenge response has failed, so domain
# owners can be aware and act accordingly.
#
# Parameters:
# - DOMAIN
# The primary domain name, i.e. the certificate common
# name (CN).
# - RESPONSE
# The response that the verification server returned
# Simple example: Send mail to root
# printf "Subject: Validation of ${DOMAIN} failed!\n\nOh noez!" | sendmail root
}
request_failure() {
local STATUSCODE="${1}" REASON="${2}" REQTYPE="${3}" HEADERS="${4}"
# This hook is called when an HTTP request fails (e.g., when the ACME
# server is busy, returns an error, etc). It will be called upon any
# response code that does not start with '2'. Useful to alert admins
# about problems with requests.
#
# Parameters:
# - STATUSCODE
# The HTML status code that originated the error.
# - REASON
# The specified reason for the error.
# - REQTYPE
# The kind of request that was made (GET, POST...)
# - HEADERS
# HTTP headers returned by the CA
# Simple example: Send mail to root
# printf "Subject: HTTP request failed failed!\n\nA http request failed with status ${STATUSCODE}!" | sendmail root
}
generate_csr() {
local DOMAIN="${1}" CERTDIR="${2}" ALTNAMES="${3}"
# This hook is called before any certificate signing operation takes place.
# It can be used to generate or fetch a certificate signing request with external
# tools.
# The output should be just the cerificate signing request formatted as PEM.
#
# Parameters:
# - DOMAIN
# The primary domain as specified in domains.txt. This does not need to
# match with the domains in the CSR, it's basically just the directory name.
# - CERTDIR
# Certificate output directory for this particular certificate. Can be used
# for storing additional files.
# - ALTNAMES
# All domain names for the current certificate as specified in domains.txt.
# Again, this doesn't need to match with the CSR, it's just there for convenience.
# Simple example: Look for pre-generated CSRs
# if [ -e "${CERTDIR}/pre-generated.csr" ]; then
# cat "${CERTDIR}/pre-generated.csr"
# fi
