Mattermost Alpha
Team Communication Service
Development Build

Mattermost is an open-source team communication service. It brings team messaging and file sharing into one place, accessible across PCs and phones, with archiving and search.

• Ask the core team anything at: http://forum.mattermost.org
• Share feature requests and upvotes: http://www.mattermost.org/feature-requests/

• Make a pull request: http://www.mattermost.org/contribute-to-mattermost/

You're installing "Mattermost Alpha", a pre-released version providing an early look at what we're building. While the core team runs this version internally, it's not recommended for production since we can't guarantee API stability or backwards compatibility.

That said, any issues at all, please let us know on the Mattermost forum at: http://forum.mattermost.org

Notes:

• For Alpha, Docker is intentionally setup as a single container, since production deployment is not yet recommended.

1. Install Boot2Docker using instructions at: http://docs.docker.com/installation/mac/
   1. Start Boot2Docker from the command line and run: boot2docker init eval “$(boot2docker shellinit)”
2. Get your Docker IP address with: boot2docker ip
3. Use sudo nano /etc/hosts to add <Docker IP> dockerhost to your /etc/hosts file
4. Run: boot2docker shellinit and copy the export statements to your ~/.bash_profile by running sudo nano ~/.bash_profile. Then run: source ~/.bash_profile
5. Run: docker run --name mattermost-dev -d --publish 8065:80 mattermost/platform
6. When docker is done fetching the image, open http://dockerhost:8065/ in your browser.

1. Follow the instructions at https://docs.docker.com/installation/ubuntulinux/ or use the summary below:

   sudo apt-get update
   sudo apt-get install wget
   wget -qO- https://get.docker.com/ | sh
   sudo usermod -aG docker <username>
   sudo service docker start
   newgrp docker

2. Start docker container:

   docker run --name mattermost-dev -d --publish 8065:80 mattermost/platform

3. When docker is done fetching the image, open http://localhost:8065/ in your browser.

1. Install docker using the following commands:

   pacman -S docker
   systemctl enable docker.service
   systemctl start docker.service
   gpasswd -a <username> docker
   newgrp docker

2. Start docker container:

   docker run --name mattermost-dev -d --publish 8065:80 mattermost/platform

3. When docker is done fetching the image, open http://localhost:8065/ in your browser.

• If you want to work with the latest bits in the repository (i.e. not a stable release) you can run the cmd:
  docker run --name mattermost-dev -d --publish 8065:80 mattermost/platform:dev

• You can update to the latest bits by running:
  docker pull mattermost/platform:dev

• If you wish to remove mattermost-dev use:
  docker stop mattermost-dev docker rm -v mattermost-dev

• If you wish to gain access to a shell on the container use:
  docker exec -ti mattermost-dev /bin/bash

1. Create a new elastic beanstalk docker application using the Dockerrun.aws.json file provided.

   1. From the AWS console select Elastic Beanstalk.
   2. Select "Create New Application" from the top right.
   3. Name the application and press next.
   4. Select "Create a web server" environment.
   5. If asked, select create an IAM role and instance profile and press next.
   6. For predefined configuration select under Generic: Docker. For environment type select single instance.
   7. For application source, select upload your own and upload Dockerrun.aws.json from docker/0.6/Dockerrun.aws.json. Everything else may be left at default.
   8. Select an environment name, this is how you will refer to your environment. Make sure the URL is available then press next.
   9. The options on the additional resources page may be left at default unless you wish to change them. Press Next.
   10. On the configuration details place. Select an instance type of t2.small or larger.
   11. You can set the configuration details as you please but they may be left at their defaults. When you are done press next.
   12. Environment tags my be left blank. Press next.
   13. You will be asked to review your information. Press Launch.

2. Try it out! 14. Wait for beanstalk to update the environment. 15. Try it out by entering the domain of the form *.elasticbeanstalk.com found at the top of the dashboard into your browser. You can also map your own domain if you wish.

There are a few configuration settings you might want to adjust when setting up your instance of Mattermost. You can edit them in config/config.json or docker/0.6/config_docker.json if you're running a docker instance.

• EmailSettings:ByPassEmail - If this is set to true, then users on the system will not need to verify their email addresses when signing up. In addition, no emails will ever be sent.
• ServiceSettings:UseLocalStorage - If this is set to true, then your Mattermost server will store uploaded files in the storage directory specified by StorageDirectory. StorageDirectory must be set if UseLocalStorage is set to true.
• ServiceSettings:StorageDirectory - The file path where files will be stored locally if UseLocalStorage is set to true. The operating system user that is running the Mattermost application must have read and write privileges to this directory.
• AWSSettings:S3* - If UseLocalStorage is set to false, and the S3 settings are configured here, then Mattermost will store files in the provided S3 bucket.
