Aptible Metadata Variables

Aptible injects the following metadata keys as environment variables:

• APTIBLE_PROCESS_TYPE

  • Represents the name of the Service this container belongs to. For example, if the Procfile defines services like web and worker.

  • Then, the containers for the web Service will run with APTIBLE_PROCESS_TYPE=web, and the containers for the worker Service will run with APTIBLE_PROCESS_TYPE=worker.

  • If there is no Procfile and users choose to use an Implicit Service instead, the variable is set to APTIBLE_PROCESS_TYPE=cmd.

• APTIBLE_PROCESS_INDEX

  • All containers for a given Release of a Service are assigned a unique 0-based process index.

  • For example, if your web service is scaled to 2 containers, one will have APTIBLE_PROCESS_INDEX=0, and the other will have APTIBLE_PROCESS_INDEX=1.

• APTIBLE_PROCESS_CONTAINER_COUNT

  • This variable is a companion to APTIBLE_PROCESS_INDEX, and represents the total count of containers on the service. Note that this will only be present in app service containers (not in pre_release, ephemeral/ssh, or database containers).

• APTIBLE_CONTAINER_CPU_SHARE

  • Provides the vCPU share for the container, matching the ratios in our documentation for ­container profiles. Format will be provided in the following format: 0.125, 0.5, 1.0, etc.

• APTIBLE_CONTAINER_PROFILE

• APTIBLE_CONTAINER_SIZE

  • This variable represents the memory limit in MB of the Container. See Memory Limits for more information.

• APTIBLE_LAYER

  • This variable represents whether the container is an App or Database container using App or Database values.

• APTIBLE_GIT_REF

• APTIBLE_ORGANIZATION_HREF

  • Aptible API URL representing the Organization this container belongs to.

• APTIBLE_APP_HREF

  • Aptible API URL representing the App this container belongs to, if any.

• APTIBLE_DATABASE_HREF

  • Aptible API URL representing the Database this container belongs to, if any.

• APTIBLE_SERVICE_HREF

  • Aptible API URL representing the Service this container belongs to, if any.

• APTIBLE_RELEASE_HREF

  • Aptible API URL representing the Release this container belongs to, if any.

• APTIBLE_EPHEMERAL_SESSION_HREF

  • Aptible API URL representing the current Ephemeral SSH Sessions this container belongs to, if any.

• APTIBLE_USER_DOCUMENT

  • Aptible injects an expired JWT object with user information.
    • The information available is id, email, name, etc.

  decode_base64_url() {
      local len=$((${#1} % 4))
      local result="$1"
      if [ $len -eq 2 ]; then result="$1"'=='
      elif [ $len -eq 3 ]; then result="$1"'=' 
      fi
      echo "$result" | tr '_-' '/+' | openssl enc -d -base64
  }
  
  decode_jwt(){
      decode_base64_url $(echo -n $2 | cut -d "." -f $1) | sed 's/{/\n&\n/g;s/}/\n&\n/g;s/,/\n&\n/g' | sed 's/^  */  /'
  }
  
  # Decode JWT header
  alias jwth="decode_jwt 1"
  
  # Decode JWT Payload
  alias jwtp="decode_jwt 2"
  

  You can use the above script to decode the expired JWT object using jwtp $APTIBLE_USER_DOCUMENT

• APTIBLE_RESOURCE_HREF

  • Aptible uses this variable internally. Do not depend on this value.

• APTIBLE_ALLOCATION

  • Aptible uses this variable internally. Do not depend on this value.
