Docker builds images automatically by reading the instructions from a Dockerfile- a text file that contains all commands, in order, needed to build a given image. A Dockerfile adheres to a specific format and set of instructions which you can find at Dockerfile reference. I created a docker container from my OS X VM Docker host. I created it using the run command and created the container based off the ubuntu:xenial image off docker hub. I'm now connected to my container after it's created and logged in as root and at the command prompt inside my container.

The following instructions use Docker to install Mattermost in Preview Mode for exploring product functionality on a single machine.

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies. The Docker team also strongly discourages using ADD to download and copy a package from a URL. Instead, it’s safer and more efficient to use wget or curl within a RUN command. By doing so, you avoid creating an additional image layer and save space. Wget Docker-compose. In a container environment, you can add similar contents to a Dockerfile: Wget In Docker Image Questions or feedback Wget In Dockerfile. See Tips and Tricks or the FAQ. Search on Stack Overflow. Add a feature request or report a problem. Create a development container definition for others to use.

Note: This configuration should not be used in production, as it uses a known password string, contains other non-production configuration settings, and does not support upgrade.

If you’re looking for a production installation with Docker, please see the Mattermost Production Docker Deployment Guide.

Setting up SMTP Email (Recommended)¶

Wget In Docker

The default single-container Docker instance for Mattermost is designedfor product evaluation, and sets SendEmailNotifications=false so theproduct can function without enabling email. To see the product’s fullfunctionality, enabling SMTP email is recommended.

To enable email, configure an SMTP email service as follows:

  1. Set up an SMTP email sending service (if you don’t yet have anSMTP service with credentials)

    • Any SMTP email service can be used, you just need the following

      information: ServerName, Port, SMTPUsername, andSMTPPassword.

      • If you don’t have an SMTP service, here are simple instructions

        to set one up with Amazon Simple Email Service(SES):

        1. Go to Amazon SESconsole thenSMTPSettings>CreateMySMTPCredentials

        2. Copy the ServerName, Port, SMTPUsername, andSMTPPassword for Step 2 below.

        3. From the Domains menu set up and verify a new domain,then enable GenerateDKIMSettings for the domain.

          1. We recommend you set up Sender PolicyFramework(SPF) and/or Domain Keys IdentifiedMail(DKIM) for your email domain.

        4. Choose a sender address like [email protected] andclick SendaTestEmail to verify setup is workingcorrectly.

  2. Configure SMTP settings

    1. Open the System Console by logging into an existing team andaccessing “System Console” from the main menu.

      • Alternatively, if a team doesn’t yet exist, go to

        http://dockerhost:8065/ in your browser, create a team,then from the main menu click System Console

    2. Go to the Authentication > Email tab and configure the following:

      1. Allow Sign Up With Email:true

    3. Go to the Notifications > Email tab and configure the following:

      1. Send Email Notifications:true

      2. Notification Display Name: Display name on email accountsending notifications

      3. Notification Email Address: Email address displayed onemail account used to send notifications

      4. SMTP Username: SMTPUsername from Step 1

      5. SMTP Password: SMTPPassword from Step 1

      6. SMTP Server: SMTPServer from Step 1

      7. SMTP Port: SMTPPort from Step 1

      8. Connection Security: TLS(Recommended)

      9. Then click Save

      10. Then click Test Connection

      11. If the test failed please look in OTHER > Logs for anyerrors that look like [EROR]/api/v4/email/test...

    4. (Optional) Go to the Security > Sign Up tab and configure the following:

      1. Enable Email Invitations:true

Sample SMTP Settings¶

Amazon SES¶

  • Set SMTP Username to [YOUR_SMTP_USERNAME]

  • Set SMTP Password to [YOUR_SMTP_PASSWORD]

  • Set SMTP Server to email-smtp.us-east-1.amazonaws.com

  • Set SMTP Port to 465

  • Set Connection Security to TLS

Postfix¶

  • Make sure Postfix is installed on the machine where Mattermost isinstalled

  • Set SMTP Username to (empty)

  • Set SMTP Password to (empty)

  • Set SMTP Server to localhost

  • Set SMTP Port to 25

  • Set Connection Security to (empty)

Gmail¶

  • Set SMTP Username to [email protected]

  • Set SMTP Password to your_password

  • Set SMTP Server to smtp.gmail.com

  • Set SMTP Port to 587

  • Set Connection Security to STARTTLS

Warning

Additional configuration is required in Google to allow SMTP email to relay through their servers.See SMTP relay: Route outgoing non-Gmail messages through Google for the required steps.

Hotmail¶

Docker
  • Set SMTP Username to [email protected]

  • Set SMTP Password to your_password

  • Set SMTP Server to smtp-mail.outlook.com

  • Set SMTP Port to 587

  • Set Connection Security to STARTTLS

Office365 / Outlook¶

  • Set SMTP Username to [email protected]

  • Set SMTP Password to your_password

  • Set SMTP Server Name to smtp.office365.com

  • Set SMTP Port to 587

  • Set Connection Security to STARTTLS

Troubleshooting SMTP¶

TLS/STARTTLS Requirements¶

Wget in dockers

If you fill in SMTP Username and SMTP Password then you must setConnection Security to TLS or to STARTTLS

Troubleshooting using Logs¶

If you have issues with your SMTP install, from your Mattermost teamsite go to the main menu and open System Console -> Logs to look forerror messages related to your setup. You can do a search for the errorcode to narrow down the issue. Sometimes ISPs require nuanced setups forSMTP and error codes can hint at how to make the proper adjustments.

For example, if System Console -> Logs has an error code reading:

Search for 5545.7.1error andClienthostrejected:Accessdenied.

Checking your SMTP server is reachable¶

Install Docker Using Wget

  • Attempt to telnet to the email service to make sure the server isreachable.

  • You must run the following commands from the same machine or virtualinstance where mattermost/bin/mattermost is located.

  • Telnet to the email server with telnetmail.example.com25. Ifthe command works you should see something like

  • Then type something like HELO<yourmailserverdomain>. If thecommand works you should see something like

Note

As we’re not installing telnet by default on the official docker images you either need to use ping on those or install telnet yourself either directly or by modifying the Dockerfile.

  2. Install Docker Compose using the online guide. You have to download the latest release from the Docker Compose Github page and put the binary on your /usr/local/bin folder. Usually, you can use the following command, replacing $dockerComposeVersion with the Docker Compose version to install:

  3. Deploy the Mattermost Docker

You can get the uid (user ID) and gid (group ID) of the Docker user by running:

Docker Install Git Wget

Wget In Docker Commands

Replace <username> with the actual username. The following setup assumes the result above is uid=1000 and gid=1000.

Set up using:

The docker-compose network that is created defaults to 172.18.0.0/16. If you need to change the default network this link provides guidelines on how to do that. If the network is already set up with the default, you need to run the following command to remove it. Then, run the command again to regenerate the default network to include the new network setting.

To verify the current Docker network use the following command to list it (you can access information about the options here):

  1. Configure TLS by following the instructions.

  2. Configure Email by following the SMTP email setup guide.

  3. (Optional) To enable enterprise features, go to System Console > Edition and License and select Start trial.

  4. Configure your Server based on the configuration settings documentation.

Once you’ve saved your configurations, start an Enterprise E20 trial via Main Menu > System Console > Edition and License > Start trial.
