docker-wait's Introduction

Docker Wait

A node.js binary that blocks until a regex match has been made with output from docker logs.

The intended use is in bash files for server deployment where you want to ensure that a docker container has fully loaded

Must be run as root (in order to read your docker logs)

###Installation

    npm install -g docker-wait

###Usage

    docker-wait [path-to-config-file.json|coffee|js]

###Config File

The binary blocks until the regex match has been with ALL listed containers

    {
      timeout: 30, // number of seconds to wait before exiting with error

      logOutput: true, // send the docker logs output to cli
      containers: {

        'container_name': /match this/g,
        'another_container_name': /Lisening on port \d{4}/
      }
    }
