How to control Docker for Mac from the CLI Stop Docker for Mac gracefully test -z '$(docker ps -q 2>/dev/null)' && osascript -e 'quit app 'Docker' Note: Requires all Docker containers in the stopped state.
Expected behavior Docker for Mac doesn't hang. Actual behavior Docker for Mac hangs. Installed docker on new MBP and after mac woke up from sleep, I noticed this issue.
I have not noticed this on my previous MBP. Docker restart got hung. I just tried again with the latest edge, 18.01.0-ce-mac48 (220004). The exact same thing still happens.
Docker for Mac: version: 18.01.0-ce-mac48 (d1778b704353fa5ba2c11c8b48a653) macOS: version 10.12.6 (build: 16G1114) logs: /tmp/230E6503-3092-4DE1-BC76-47C03F92A4D5/20133.tar.gz failure: docker ps failed: (Failure 'docker ps: timeout after 10.00s') OK db.git OK vmnetd OK dns OK driver.amd64-linux OK virtualization VT-X OK app OK moby OK system OK moby-syslog OK kubernetes OK env OK virtualization kern.hvsupport OK slirp OK osxfs OK moby-console OK logs ERROR docker-cli docker ps failed OK menubar OK disk Diagnostic ID: 230E6503-3092-4DE1-BC76-47C03F92A4D5. I'm having the same issue. Docker for Mac is a better experience than virtual box was, what without the intermediate VM and all, but this makes it torture.
Docker rmi has about a 50% chance of hanging, so when I run out of space it's an endless cycle of rmi, HANG, stop docker, start docker, rmi, rmi, HANG. Of course, when it's hanging diagnostics doesn't work. Still seeing this in 18.03.0-ce-rc1-mac54 (23022).
Usually when this happens, trying to restart or quit-then-start Docker via the Docker for Mac GUI will hang in the 'Docker is starting' state, and I have to force quit the com.docker.hyperkit process then open Docker for Mac to get Docker into a usable state again. Looking around for other solutions, I came across, which points (at the end) to.
This may not be the same issue as what I'm experiencing since people there report that rolling back to 17.09 fixes the issue for them, while I was already experiencing this problem in 17.06. I don't believe that I'm seeing this due to tty, resource, or network issues either. Diagnostic ID: 230E6503-3092-4DE1-BC76-47C03F92A4D5 I've been trying to dig deeper into this over the last couple days - one thing I've been checking is what's going on inside Docker by using screen /Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty and watching the kernel log messages when this behavior occurs. The first time I did this I was seeing NMI watchdog: BUG: soft lockup - CPU#3 stuck for 23s! Almost by accident, I think I've discovered a workaround for my particular case. I decided to try running the same docker-compose setup on my (relatively under-resourced) MacBook Pro instead of my iMac, to see what happened with the latest Docker edge (previously I had encountered the same behavior on both machines). Since the internal (SSD) drive on the MBP was running out of space, I decided to try moving the Docker disk image location (the Docker.qcow2 file) to an external USB drive, using the Docker for Mac UI.
Miraculously, I was able to do everything I needed to do without Docker crashing or becoming completely unresponsive. This gave me the idea to try the same thing on my iMac today - and after moving the Docker disk image off the internal 3TB Fusion Drive to an external USB drive, I seem to be able to do everything I need to do without having Docker crash or become completely unresponsive.
All drives (internal and external) are formatted Mac OS Extended Journaled (case-insensitive), and the internal drives report a S.M.A.R.T. Status of 'Verified' with no other programs appearing to have issues using them.
Perhaps this is consistent with the ATA/SCSI errors causing a CPU/task stall in my logs above, though I'm not sure what the root cause or error is. The thing consistent across both machines is that the problematic drive for Docker is an internal SSD or Fusion Drive. Thanks for the logs above.

I'm not sure if the leading./ or the trailing / is what's helping you.
In my case I'm simply excluding all /packages/, (with a leading /). The documentation specifically allows this, (and.dockerignore seems to be compatible): A leading slash matches the beginning of the pathname.
For example, '/.c' matches 'cat-file.c' but not 'mozilla-sha1/sha1.c'. Note that, for me, when the symlinks were present and processed, even docker build -f Dockerfile.
Was hanging with no output (and docker-compose up -build emitted building web and then hung). However docker build -f -.
Ndevenish, You may have hit on something in your earlier comment pertaining to 'mainly happens after longer builds, or coming back to use docker after awhile.' Sometimes this problem occurs because of a slow network condition. In cases like a slow network condition, developers have found that setting COMPOSETIMEOUT to a higher value works well. What one would have to do is to ascertain the current value, and then raise it. However, sufficient testing should be performed to determine an appropriate setting. I see the same issue as originally described.
I can only reproduce on an adhoc basis. When building images, if there are problems, I clean up afterwards. I rmi a few images, rm'ing stopped containers as and when required. Invariably after I've rmi'd 3-4 images, Docker hangs - not just ps. I have to restart Docker. Once I've restarted, the last command works fine (and quickly too - it feels like previous commands were becoming more sluggish before Docker hung completely).
If I can provide any more information please let me know. This behaviour happened in 17.x as well.

Sometimes this problem occurs because of a slow network condition. In cases like a slow network condition, developers have found that setting COMPOSETIMEOUT to a higher value works well. Thanks for the suggestion, but my job wasn't doing network access at the stage where it failed (it was deliberately split into one step that did network downloads, then a long build of all dependencies - the latter where it failed). FWIW I haven't seen this problem for a while now - including on the original jobs that caused it quite reliably.
I never switched away from qcow2 (no time to backup volumes and images using), just updating docker. Docker on OSX Sierra 10.12.5, upgrade to latest, docker hangs forever at startup now.

Had another occurrence of a seemingly hanging docker-compose setup. CPU was spinning 100%. Turns out that processes within the container kept eating 100% RAM, were then killed by the OOM killer, restarted, killed by the OOM killer, restarted. It wasn't obvious at first as the logging of the application within the container did not give it away easily. I then found the OOM killers log messages it in the OS X 'Console' application (filter for docker!). The resolution was straight forward: allow docker containers to eat more RAM (Docker Preferences - Advanced). I could imagine that more users suffer from such a OOM-crash-OOM-crash cycle without noticing.
Maybe add this to the FAQ? I wasn't even aware that Docker for Mac constrains the overall RAM consumption to 2GB, IMO an unreasonable low default. I have been experiencing more lock-ups since the latest update to Docker for Mac.
In my case it appears that it happens when I am performing a lot of I/O activity: either disk or network. This reliably seems to cause the main docker engine to stop responding and freezes any process (running containers, called commands etc) and requires a full restart of Docker. In my case these are not RAM or disk limit issues (docker file is 128GB, using about 30GB; processes are using less than 40MB and have max thread counts).

Before a freeze I do observe that docker commands e.g. Docker-compose log / ps start responding much slower. They take a noticeable time before they do anything and once this starts, a total lock-up of docker is usually only a few minutes away. The only log information I have is a wakeupsresource.diag log that coincides with each hang (slightly trimmed): Date/Time: 2018-12-21 09:09:47 -0500 End time: 2018-12-21 09:09:53 -0500 OS Version: Mac OS X 10.14.2 (Build 18C54) Architecture: x8664h Command: com.docker.hyperkit Path: /Applications/Docker.app/Contents/Resources/bin/com.docker.hyperkit Version:???
Docker Basics for Amazon ECS Docker is a technology that allows you to build, run, test, and deploy distributed applications that are based on Linux containers. Amazon ECS uses Docker images in task definitions to launch containers on Amazon EC2 instances in your clusters. For Amazon ECS product details, featured customer case studies, and FAQs, see the.
The documentation in this guide assumes that readers possess a basic understanding of what Docker is and how it works. For more information about Docker, see and the. Note If you already have Docker installed, skip to. Docker is available on many different operating systems, including most modern Linux distributions, like Ubuntu, and even Mac OSX and Windows.
For more information about how to install Docker on your particular operating system, go to the. You don't even need a local development system to use Docker. If you are using Amazon EC2 already, you can launch an Amazon Linux 2 instance and install Docker to get started. To install Docker on an Amazon Linux 2 instance. Launch an instance with the Amazon Linux 2 AMI.
For more information, see in the Amazon EC2 User Guide for Linux Instances. Connect to your instance. For more information, see in the Amazon EC2 User Guide for Linux Instances. Update the installed packages and package cache on your instance. Cannot connect to the Docker daemon. Is the docker daemon running on this host? Create a Docker Image Amazon ECS task definitions use Docker images to launch containers on the container instances in your clusters.
In this section, you create a Docker image of a simple web application, and test it on your local system or EC2 instance, and then push the image to a container registry (such as Amazon ECR or Docker Hub) so you can use it in an ECS task definition. To create a Docker image of a simple web application. Create a file called Dockerfile.
A Dockerfile is a manifest that describes the base image to use for your Docker image and what you want installed and running on it. For more information about Dockerfiles, go to the. FROM ubuntu:16.04 # Install dependencies RUN apt-get update RUN apt-get -y install apache2 # Install apache and write hello world message RUN echo 'Hello World!' /var/www/html/index.html # Configure apache RUN echo '. /etc/apache2/envvars' /root/runapache.sh RUN echo 'mkdir -p /var/run/apache2' /root/runapache.sh RUN echo 'mkdir -p /var/lock/apache2' /root/runapache.sh RUN echo '/usr/sbin/apache2 -D FOREGROUND' /root/runapache.sh RUN chmod 755 /root/runapache.sh EXPOSE 80 CMD /root/runapache.sh This Dockerfile uses the Ubuntu 16.04 image. The RUN instructions update the package caches, install some software packages for the web server, and then write the 'Hello World!' Content to the web server's document root.
The EXPOSE instruction exposes port 80 on the container, and the CMD instruction starts the web server. Build the Docker image from your Dockerfile. If you are using an EC2 instance, this is the Public DNS value for the server, which is the same address you use to connect to the instance with SSH. Make sure that the security group for your instance allows inbound traffic on port 80.
If you are running Docker locally, point your browser to. If you are using docker-machine on a Windows or Mac computer, find the IP address of the VirtualBox VM that is hosting Docker with the docker-machine ip command, substituting machine-name with the name of the docker machine you are using.
Note The get-login command is available in the AWS CLI starting with version 1.9.15; however, we recommend version 1.11.91 or later for recent versions of Docker (17.06 or later). You can check your AWS CLI version with the aws -version command. If you are using Docker version 17.06 or later, include the -no-include-email option after get-login. If you receive an Unknown options: -no-include-email error, install the latest version of the AWS CLI. For more information, see in the AWS Command Line Interface User Guide.
Important When you execute this docker login command, the command string can be visible to other users on your system in a process list ( ps -e) display. Because the docker login command contains authentication credentials, there is a risk that other users on your system could view them this way. They could use the credentials to gain push and pull access to your repositories. If you are not on a secure system, you should consider this risk and log in interactively by omitting the -p password option, and then entering the password when prompted. Push the image to Amazon ECR with the repositoryUri value from the earlier step.
