I'm trying to use ClickHouse with docker on Mac OS. I use next command:
docker run -d -p 8123:8123 --rm --name some-clickhouse-server -v /my/config/path/config.xml:/etc/clickhouse-server/config.xml --ulimit nofile=262144:262144 yandex/clickhouse-server:latest
Container successfully started, but when I try to connect to it by http curl 'http://localhost:8123' I have an error:
Failed to connect to localhost port 8123: Connection refused
When I connect to Clickhouse from Clickhouse-client (also using docker image) everything is OK
I ran Clickhouse-server image in -it mode, installed curl, started server and tried to connect clickhouse-server from inside of container, it's OK too
Also I tried to modify config.xml (which was copied from docker image) settings for listen_host (::, 0.0.0.0, ::1, 127.0.0.1)
and for every setting I tried to connect by curl for localhost, 127.0.0.1, 0.0.0.0 - nothing of this solved my problem
Normally, docker desktop write these details of host and container to /etc/hosts, after adding the clickhouse-service as follows has resolved this issue.
127.0.0.1 localhost clickhouse-service
I used Docker Toolbox on Mac OS (in conjunction with VirtualBox). So, I've migrated to Docker Desktop and this has solved my problem

I use Docker CE for Windows on latest Windows 10 and have built an image with a
script that runs a test against a web server.
(A litmus test suite for a WebDAV server to be exact, but I think the problem
is general.)
I run the web server on a Powershell console:
> wsgidav -p 8080 -H localhost
21:04:19.107 - <13348)> wsgidav INFO : Running WsgiDAV/3.0.0a3 Cheroot/6.4.0 Python/3.6.5
21:04:19.107 - <13348)> wsgidav INFO : Serving on http://localhost:8080 ...
From another Powershell console, I run my script in a Docker container (using FROM alpine).
The script starts and tries to access the endpoint, but does not succeed:
> docker pull mar10/litmus
> docker run --rm -p 8080:8080 mar10/litmus http://gateway.docker.internal:8080
-> running `basic':
0. init.................. FAIL (connection refused by `gateway.docker.internal' port 8080: Operation timed out)
I tried so far
Using the gateway.docker.internal hostname
using -p PORT:PORT
using --net=host
restarting the docker daemon (which interestingly sometimes also was neccessary to
fix timeouts in docker pull)
different IP addresses for the web server (127.0.0.1, localhost, 0.0.0.0, local IP)
Nothing worked so far (although the failure message may be different).
Maybe I just missed a working combination of the above, or any other trick?
FWIW, I was able to solve it by building the container with the --network host option and use a real IP of the client (instead of localhost or 0.0.0.0).

I'm runner Docker for OSX, and having trouble getting the Docker remote API to work.
My situation is this:
Docker daemon running natively on OSX (https://www.docker.com/products/docker#/mac, so not the boot2docker variant)
Jenkins running as docker image
No I want to use the Jenkins docker-build-step plugin to build a docker image, but I want it to use the docker daemon on the host machine, so in Jenkins settings, DOCKER_URL should be something like :2375. (Reason for this is I don't want to install docker on the jenkins container if I already have it on my host machine).
Is there a way to to this or is de Docker for Mac currently not supporting this? I tried fiddling with export DOCKER_OPTS or DOCKER_HOST options but still get a Connection refused on calling http://localhost:2375/images/json for example.
Basicly the question is more about enabling the Docker for OSX remote api, with use case calling it from a Jenkins docker container.
You could consider using socat. It solved my problem, which seem to be similar.
socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock &
This allows you to access your macOS host Docker API from a Docker container using: tcp://[host IP address]:2375
On macOS socat can be installed like this:
brew install socat
See here for a long discussion on this topic: Plugin: Docker fails to connect via unix:// on Mac OS X
If you already added an SSH public key to your remote server, then you can use this ssh credentials for your docker connection, too. You don't need to configure the remote api on the server for this approach.
When connecting to macOS Docker Desktop, you could use ssh (after you have enabled it on Mac)
docker -H ssh:user#192.168.64.1 images
or
export DOCKER_HOST=ssh:user#192.168.64.1
docker images
I had the same issue but with mysql. I needed to expose the port of my docker hosts on port 43306 to docker image mysql running on port 3306.
Solution:
Create your docker image with -p parameter.
Example:
#> docker run -p 0.0.0.0:43306:3306 --name mysql-5.7.23xx -e MYSQL_ROOT_PASSWORD=myrootdba -d mysql/mysql-server:5.7.23 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
Now I can connect from my host docker server on port 43306 to mysql docker image.
In my current job we have development environment made with docker-compose.
One container is nginx, which provide routing to other containers.
Everything seems fine and work to my colleague on windows and osx. But on my system (osx El Capitan), there is problem with accessing nginx container on port 80.
There is setup of container from docker-compose.yml
nginx:
build: ./dockerbuild/nginx
ports:
- 80:80
links:
- php
volumes_from:
- app
... and more
In ./dockerbuild/nginx there is nothing special, just nginx config as we know it from everywhere.
When I run everyting with docker-compose create and docker-compose start. Then docker ps give me
3b296c1e4775 docker_nginx "nginx -g 'daemon off" About an hour ago Up 47 minutes 0.0.0.0:80->80/tcp, 443/tcp docker_nginx_1
But when I try to access it for example via curl I get error. curl: (7) Failed to connect to localhost port 80: Connection refused
I try to run container with port 81 and everything works fine.
Port is really binded to docker
22:47 $ sudo lsof -i -n -P | grep TCP
...
com.docke 14718 schovi 38u IPv4 0x6e9c93c51ec4b617 0t0 TCP *:80 (LISTEN)
...
Firewall in osx is turned off and I have no other security.
if you are using docker-for-mac:
Accessing by localhost:80 is correct, though you still have to ensure you do not have a local apache/nginx service running. Often leftovers from boxen/homebrew exist binding that port, because thats what developers did back then :)
if you are using dockertoolbox/virtualbox/whatever hypervisor
You will not be able to access it by localhost, by by the docker-machine ip, so write docker-machine ip default and the use http://$ip:80 in your browser
if that does not help
Ensure your nginx container actually does work, so connect to the container: docker exec -i -t <containerid> bash
and then run ps aux nginx or if telnet is installed try to connect to localhost
Solved!
Problem was, that long long time ago I installed pow (super simple automated rails server which run application on app_name.local domain). And this beast left LaunchAgent script which update pf to forward port 80 to pow port.
In my current job we have development environment made with docker-compose.
A privilege to use.
[W]hen I try to access [nginx on port 80] for example via curl I get error.
Given there's nothing from causing you from accessing docker on your host os you should look at the app running inside the container to ensure it's binding to the correct host, e.g. 0.0.0.0 and not localhost.
For example, if you're running Nuxt inside a container with nuxt-ts observe Nuxt will default to localhost thereby causing the container not to connect to the docker network whereas npx nuxt-ts -H 0.0.0.0 gets things squared away with the container's internal server connecting to the ip of the docker network used (verify ip like docker container inspect d8af01990363).
I have docker toolbox 1.8.2c installed on my Mac running yosemite. If I launch hello-world-nginx from the docker hub in Kitematic, I can connect to its TCP port without an issue.
When trying to do the same thing from the CLI, I can't connect. Why?
Here is what I am running on the docker CLI, which looks to me to be pretty standard:
docker run -d -i -t -P kitematic/hello-world-nginx /bin/sh
In the case above, docker ps shows that port 80 is mapped to 0.0.0.0:32769. So I try and connect on 192.168.99.100:32769 (that's my docker machine IP) and I can't connect.
I want to use the CLI so I can set the hostname/fqdn on the container, which it doesn't look like Kitematic supports. Here is another thing I tried, with the IP address of my docker machine in the args:
docker run -d -i -t -p 192.168.99.100:32769:80 -h nginx.example.com kitematic/hello-world-nginx /bin/sh
This doesn't work either.
In each case, the container starts successfully and I can attach to it with out an issue.
What am I doing wrong?
I had the same problem, but in windows 10 pro witn the same image kitematic/hello-world-nginx. Kitematic was open a wep page by default with Internet Explorer and the message was inmediatetly can't connect, later I tried with another web browers, chrome, and it worked. maybe if you try with another web browser, this problem can be solved.
We are trying to use docker to run nginx but for some reason I'm unable to access the nginx web server running inside the docker container.
We have booted a Docker Container using the following Dockerfile: https://github.com/dwyl/learn-docker/blob/53cca71042482ca70e03033c66d969b475c61ac2/Dockerfile
(Its a basic hello world using nginx running on port 8888)
To run the container we used:
docker run -it ubuntu bash
we determined the Container's IP address using the docker inspect command:
docker inspect --format '{{ .NetworkSettings.IPAddress }}' a9404c168b21
which is: 172.17.0.11
when I try to visit the container's IP address and the nginx port in a browser http://172.17.0.11:8888/ we get ERR_CONNECTION_TIMED_OUT
or using curl:
curl 172.17.0.11:8888
curl: (7) Failed to connect to 172.17.0.11 port 8888: Connection refused
To attempt to solve this we googled extensively but suspect we might be asking the "wrong" questions...
You shouldn't be trying to hit the IP address of the container, you should be using the IP address of the host machine.
What you are missing is the mapping of the port of the host machine to the port of the container running the nginx server.
Assuming that you want to use port 8888 on the host machine, you need a parameter such as this to map the ports:
docker run ... -p 8888:8888 ...
Then you should be able to access you server at http://<HOST_MACHINE_IP>:8888
EDIT: There is another gotcha if you are running on a Mac. To use Docker on a Mac it's common to use boot2docker but boot2docker adds in another layer. You need determine the IP address of the boot2docker container and use that instead of localhost to access nginx.
$ boot2docker ip
The VM's Host only interface IP address is: <X.X.X.X>
$ wget http://<X.X.X.X>:8888
...
Connecting to <X.X.X.X>:8888... connected.
HTTP request sent, awaiting response... 200 OK
Reference: https://viget.com/extend/how-to-use-docker-on-os-x-the-missing-guide
EDIT: ... or with docker-machine the equivalent command would be docker-machine ip <machine-name> where <machine-name> is likely to be "default".
You may need to check if your container is running:
docker ps ( you should have an active container)
If no container is active:
docker run -p 80:80 -it /bin/bash
you will then be on your image terminal
start nginx - sudo service nginx start
ctrl p + ctrl q to quit docker without exiting the container
if you are on mac and using boot2docker you cannot use localhost to check your running nginx
so use boot2docker ip
browse using the boot2docker ip
