In this article, we will show you how to install Docker CE (Community Edition), create and run Docker containers on Ubuntu distribution. Installing Docker CE (Community Edition) in Ubuntu. To install Docker CE, first, you need to remove older versions of Docker were called docker, docker.io, or docker-engine from the system using the. Install Docker using the Ubuntu online guide or these instructions: sudo apt-get update sudo apt-get install wget wget-qO-https: // get.

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

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.

Note

Setting up SMTP Email (Recommended)¶

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 mattermost@example.com 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 your_email@gmail.com

• 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¶

• Set SMTP Username to your_email@hotmail.com

• 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 your_email@hotmail.com

• 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¶

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¶

• 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.

• Download adobe acrobat for mac catalina. 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

Install Docker Using Wget

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.
