UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=60)

Hi since yesterday I've been running into this error while doing docker-compose up

Full Error Message

Device-Tracker $ docker-compose up

Docker Version
Docker for Mac: 1.12.0-a (Build 11213)
Machine info
MacBook Air (13-inch, Early 2015)
Processor: 1.6 GHz i5
Memory: 4GB 1600 MHz DDR3
macOS: Version 10.11.6 (Build 15G1004)

Attempts

• Everything still works on colleagues' machine, they are using MacBook Pro
• Increased Docker CPU from 2 to 3, and 2GB RAM to 3GB, still error
• Removed All Docker containers & images, and rebuild everything, still error

[bodadotsh]

tried this

export DOCKER_CLIENT_TIMEOUT=120
export COMPOSE_HTTP_TIMEOUT=120

and it seems to fix the issue for now

Other solutions people mentioned in this thread:

• Restart Docker
• Increase Docker CPU & memory

Does it happen if you turn off your WiFi? Could be related to docker/docker-py#1076.

Another theory, if your service has tty: True enabled, could be #3106

I'm seeing exactly the same problem with latest beta for Mac. Same error if I run docker-compose create

Could this be related to having one very large layer in the image? (a very lengthy npm install operation that takes about a minute to be flattened into a layer when docker builds the image)

[benferns]

We are also seeing this issue using a docker compose file with 6 containers [docker-compose version 1.8.1, build 878cff1] on both windows and mac [Version 1.12.2-rc1-beta27 (build: 12496)
179c18cae7]

Increasing resources available to docker seems to reduce the chance of it happening (as does extending the timeout vars) , but its never eliminated.

We also have some large-ish layers (240MB is the largest, the main package install command) and we are binding to a host directory with 120MB of files across a couple of containers.

[gvilarino]

From different attempts at working around this, I found something that might shed some light on a possible fix:

At first my scenario looked a bit like this:

app:
  build: .
  volumes:
    - ${PWD}:/usr/src
    - /usr/src/node_modules

My mounted path included many directories with big, static files that I didn't really need mounted in terms of code reloading. So i ended up swapping for something like this:

app:
  build: .
  volumes:
    - ${PWD}:/usr/src
    - /usr/src/static  # large files in a long dir structure
    - /usr/src/node_modules

This left out of the runtime mounting all my big static files, which made the service start way faster.

What I understand from this is: the more files you mount, especially the larger they are (images in the MBs instead of source files in the Bs/KBs), loading times go up by a lot.

Hope this helps

I am seeing this timeout issue every single week, usually after an idle weekend, while I was trying to connect to me containers, it timed out...
I have to terminate the running docker proc and restart it to work around....

It happens to me every time I try to restart the containers because they are not responding anymore after a day. I'm not sure if my case has to do with the mounting since I am trying to stop the containers.

If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

Thanks @gvilarino, I believe the big files mounting is the cause of this issue on my linux server. Your snippet could be a workaround if the big files are not needed in container.

However, I wonder why mounting is slow in Docker? Maybe it triggers disk copy? But why?

[gvilarino]

@cherrot I wouldn't say I'm extremely proficient in the subject, but I believe this has to do with the storage driver used by Docker and how it works internally for keeping layers in order. Use docker info to see what storage driver your daemon is using (probably aufs, which is the slowest) and depending on your host OS, you may change it so something else (overlay being a better choice, if supported). There are faster alternatives like LCFS but they aren't commercially supported by Docker so you'd be on your own there.

We are also seeing this time-out. It seems also due to the volumes we are using.

We need some containers to access some SMB network shares. So we mounted those share on the host system, and bind-mounted them inside the container. But sometimes the communication between the Windows Server and our Linux host is stalled (see https://access.redhat.com/solutions/1360683) and this is blocking the starting or stopping of our container which just time-out after awhile.

I do not have a fix yet. I'm looking for a volume plugin which support SMB, or to make the stall communication problem on SMB going away. but no real solution yet.

FWIW: For the people landing here through search engine finding their resolvement, I've been able to fix this simply by the did you try turning it off and on again? method; I've restarted my Docker Mac OS client.

+1 on that, I am running stress testing on my instance which runs 4 containers and docker hangs even for docker ps -a so i'm trying to restart the containers but i am getting
UnixHTTPConnectionPool(host='localhost', port=None): Read timed out and

Only if im restarting the docker service it seems to be resolved, any ideas?
