Failed Port Is Already Allocated Issue 1114 Docker For Mac Github 6,1/10 4977 reviews

Overview¶

Feb 27, 2018 This doesn’t seem to agree with the way Docker works. A fast startup simply loads the hibernation file (Hiberfil.sys) into memory to restore the previously saved image of the Windows kernel.

But in some cases it might not work even though you don't have any containers that are running in the port.You can check the running containers using docker ps command and can see all the containers that were not cleared but exited before using docker ps -a command. Logs and troubleshooting. Estimated reading time: 16 minutes. This page contains information on how to diagnose and troubleshoot Docker Desktop issues, request Docker Desktop support (Pro and Team plan users only), send logs and communicate with the Docker Desktop team, use our forums and Success Center, browse and log issues on GitHub, and find workarounds for known problems.

This page describes using ISLE-DC to launch Islandora as a suite of Docker Containers (ISLE). This is an alternative to the Islandora Ansible Playbook, which creates the Islandora stack on a single virtual machine. At the end of this tutorial, you will have a local development environment, and be able to use Docker to launch, shut down, and edit your environment.

What is ISLE?¶

ISLE, or ISLandora Enterprise, is a community initiative to ease the installation and maintenance of Islandora by using Docker. It was an initiative of the Islandora Collaboration Group, first using Islandora 7.x, and later with Islandora 8.x. The code for the Islandora Enterprise 8 Prototype (ISLE 8, sometimes just ISLE) is now under the purview of the Islandora Foundation. ISLE may also refer to the ISLE system for Islandora 7.

Why use Docker?¶

Docker is a way to separate out the 'state' of your site (i.e. all the content, files, and configurations that you've entered) from the underlying software that runs it (e.g. webserver, database engine, etc). This allows for easier upgrades, faster development, and more flexible deployment.

Where is ISLE 8?¶

ISLE 8 is a suite of Docker containers that run the various components of Islandora required by Islandora Defaults: drupal, fedora, solr, alpaca, crayfish, matomo, etc. The individual containers are created (and automatically pushed to Docker Hub) by ISLE BuildKit.

How do I install ISLE?¶

Install ISLE locally or remotely using the Docker Compose scripts (ISLE-DC) at (Islandora-Devops/isle-dc). These are instructions to pull down and configure the necessary containers from Docker Hub. Unlike the Islandora Playbook, this method does not require Ansible, or (for local installations) VirtualBox. Like the Playbook, it has been optimized for development environments but in theory could be used in production.

These instructions describe using ISLE-DC locally to create a development Islandora sandbox. More detailed configuration options are described in the project's README.

Requirements¶

  • A computer that can run Docker (version 19.x+) and has at least 8GB of RAM (ideally 16GB)
  • An administrator account
  • (Mac OS) Apple Developer Tools
  • (Windows) The following setup has been tested:
    • Windows 10
    • Ubuntu 20.04 running on WSL 2
    • GNU make, run sudo apt update and sudo apt install make to install
    • Docker Desktop for Windows, using the WSL 2 based engine (Settings > General) and with the WSL integration active for Ubuntu (Settings > Resources > WSL integration)
  • If using make dev, see the README for other requirements.

What are we missing?

Are you, or your computer, new to spinning up development sandboxes? Do you have wisdom about installing make on Windows? We suspect these requirements may be incomplete and your experience would be appreciated at Issue #1640.

Installing Docker¶

To see if you have Docker installed, type docker --version in a terminal.

If you need to install Docker, we recommend using the application Docker Desktop. It provides a GUI for managing Docker container in Windows and MacOS, along with the Docker engine and suite of command-line tools. Linux users don't get a desktop client, but can download the Engine and command-line tools from that same link.

There is also a legacy project called Docker Toolbox which may be of interest if your machine cannot run Docker Desktop, or if you already have it installed.

Memory, Processors, and Swap Requirements

To run ISLE on Docker Desktop, you must increase the resources allocated to the software. See Docker docs on setting resources on Windows (see note on how to allocate/restrict memory when using WSL 2) or setting resources on Mac.

CPUs (processors): The CPUs allowed to Docker Desktop are still shared with the host machine, so increasing this to the maximum value should allow both the Docker containers and your host machine to run simultaneously.

Memory (RAM): This memory is completely dedicated to Docker while Docker Desktop is running, so do not allocate more than you can spare and still run your host machine. Windows users may not require as much memory for Docker as Mac users. Current suggestions for memory allocated to Docker Desktop are below, but please edit this document if you have new information.

  • Sandbox (make): 4GB
  • Development (make dev): 8GB
  • Production or production-like development: 16GB

Swap: Swap space is space borrowed from your hard disk drive to serve as makeshift RAM as needed. If you cannot provide as much RAM as you would like, increase this as is reasonable given your free disk space.

Launching Islandora with Docker¶

Summary: Using git, clone the isle-dc project. In that directory, enter the command make (or make dev - see note) to build the docker infrastructure. Then use the command docker-compose up -d to start the containers.

ISLE-DC variants: make vs make dev

Failed Port Is Already Allocated Issue 1114 Docker For Mac Github Software

The make command alone will spin up a sandbox-like version of ISLE, but only with a front end. The code files will be inaccessible, and you will not be able to install additional modules or themes. The make dev command creates a full-fleged development environment. It will copy the active Drupal codebase locally in a way that is also live to the ISLE site. This method takes longer (and may require multiple retries if your internet connection is spotty) but is required if you will be testing pull requests or writing code.

Results of make:

Troubleshooting - Docker Versions

If you get an error such as: ERROR: Version in './docker-compose.activemq.yml' is unsupported., then you need to upgrade Docker. Enter the command make clean before re-attempting to make.

Troubleshooting - re-attempting make

If make fails for any reason, enter make clean before attempting to make again. If not, you may see an error such as: ERROR: Top level object in './docker-compose.yml' needs to be an object not '<class 'NoneType'>'.

Troubleshooting - docker containers exit without warning

If you notice some Docker containers drop (exited(0)), and (in Docker Desktop) the isle-dc app icon is yellow instead of green, try increasing the resources allocated to Docker (see note above).

Development version - access the codebase

If you used make dev, then you will have a new directory in the current (isle-dc) directory named codebase, containing the live Drupal root folder (containing your Drupal's composer files and the web/ subdirectory). Mathtype for mac office 2016 crack.

Once make has successfully completed, launch the ISLE containers using docker-compose up. The -d flag allows you to return to using the command line. Without it, your shell will be stuck in the docker-compose process as long as the containers are running.

Troubleshooting - connection timed out (Mac).

If you are using Docker Desktop for Mac, and get timeout errors when spinning up the containers (during docker-compose up -d or during make dev) such as this:

ERROR: for isle-dc_mariadb_1 UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=480)

you can try quitting Docker completely (make sure there is no whale icon in your top toolbar - may need to select 'Quit' from the whale icon itself) and then restart Docker.

Visiting your Islandora site¶

Direct a browser to https://islandora.traefik.me/. If your containers are still 'spinning up', you will see a white screen with the words 'Bad Gateway'. This often lasts 2-5 minutes, and should be shorter for subsequent launches. If it takes more than a few minutes, check to make sure that none of your containers have failed to launch (see note above on 'Troubleshooting - docker containers exit without warning'). When all containers are ready, you should see a basic Drupal login screen.

To log in:

  • username: admin
  • password: password

Note

docker logs -tf isle-dc_drupal_1 shows Docker logs for the 'drupal' container, which will continue to have new log entries as long as the drupal box is still starting up. When it gets to confd using 'env' backend, you're done. docker-compose logs is like a firehose, showing the log messages from all containers.

Spinning down your Islandora site¶

To shut down the containers without destroying your site, use docker-compose down. To also destroy your 'state' (i.e. your content, your database, your files), use docker-compose down -v.

Editing Code in Docker¶

If you used make dev then the drupal root folder is in a new directory in the isle-dc folder named codebase. This is live and editable in whatever development environment you would like. If you just did make, you will need to spin down your containers with -v to destroy your state before starting a new one with make dev.

Editing code for the back-end processes (alpaca, milliner, etc) is more complicated. Please ask on the #isle Slack channel and help us improve this documentation!

Testing a Pull Request¶

Islandora modules in the codebase/web/contrib/modules folder are already set up with git and the origin remote is the canonical Islandora repository. You can follow the command-line instructions for testing pull requests available on Github. When finished, don't forget to git checkout main (or the default branch if not named main) so you can pull new code.
