Docker Container Failed For Linux Built On Macos

 

Lets explore the relationship between the “Container Host” and the “Container OS” and how they differ between Linux and Windows containers.

Using your command line tool, SSH into your NAS, then write: cd /path/to/docker-compose touch dockerupdate.sh docker docker-compose pull sleep 60 COMPOSEHTTPTIMEOUT=360. Mar 13, 2020  tl;dr: Docker's default bind mount performance for projects requiring lots of I/O on macOS is abysmal.It's acceptable (but still very slow) if you use the cached or delegated option. But it's actually fairly performant using the barely-documented NFS option! Ever since Docker for Mac was released, shared volume performance has been a major pain point.

Some Definitions:

Expected behavior Any docker container listed in docker ps -a can be removed with docker rm. Actual behavior Docker containers are continually listed as Status: Removal In Progress Performing the docker rm produces: $ docke. Docker enables developers to deploy applications inside containers for testing code in an environment identical to production. PhpStorm provides Docker support using the Docker plugin. The plugin is bundled and enabled by default. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins page as described in Manage plugins. The dockerfile defined in this example takes the following steps: Start FROM the pre-existing node:current-slim image. This is an official image, built by the node.js vendors and validated by Docker to be a high-quality image containing the Node.js Long Term Support (LTS) interpreter and basic dependencies.; Use WORKDIR to specify that all subsequent actions should be taken from the.

  • Container Host: Also called the Host OS. The Host OS is the operating system on which the Docker client and Docker daemon run. In the case of Linux and non-Hyper-V containers, the Host OS shares its kernel with running Docker containers. For Hyper-V each container has its own Hyper-V kernel.
  • Container OS: Also called the Base OS. The base OS refers to an image that contains an operating system such as Ubuntu, CentOS, or windowsservercore. Typically, you would build your own image on top of a Base OS image so that you can take utilize parts of the OS. Note that windows containers require a Base OS, while Linux containers do not.
  • Operating System Kernel: The Kernel manages lower level functions such as memory management, file system, network and process scheduling.

Now for some pictures:

In the above example

  • The Host OS is Ubuntu.
  • The Docker Client and the Docker Daemon (together called the Docker Engine) are running on the Host OS.
  • Each container shares the Host OS kernel.
  • CentOS and BusyBox are Linux Base OS images.
  • The “No OS” container demonstrates that you do not NEED a base OS to run a container in Linux. You can create a Docker file that has a base image of scratch and then runs a binary that uses the kernel directly.
  • Check out this article for a comparison of Base OS sizes.

In the above example

  • The Host OS is Windows 10 or Windows Server.
  • Each container shares the Host OS kernel.
  • All windows containers require a Base OS of either nanoserver or windowsservercore.

In the above example

  • The Host OS is Windows 10 or Windows Server.
  • Each container is hosted in its own light weight Hyper-V VM.
  • Each container uses the kernel inside the Hyper-V VM which provides an extra layer of separation between containers.
  • All windows containers require a Base OS of either nanoserver or windowsservercore.

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.

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

  • 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.

  • 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.
