Please see the command below:
docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Password1" -p 1433:1433 -d microsoft/mssql-server-linux:2017-latest
After I run this command I can connect to the database using SQL Studio manager as shown below:
I can also connect using: 192.168.99.100,1433.
Next I remove the container and execute the following command:
docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Password1" -p 600:600 -d microsoft/mssql-server-linux:2017-latest
I have made up the port here. Now, please see the screenshot below:
1) Why is the tcp port 1433?
2) Why can I not connect to the database on port 500?
I realise the documentation tells you to use port 1433 as shown here: https://hub.docker.com/r/microsoft/mssql-server-linux/. However, it does not tell me why.
(1) The image Dockerfile presumably says EXPOSE 1433 because that's the port the server listens on; the bare 1433/tcp output in docker ps means that port isn't published to the host.
(2) When you docker run -p 600:600, you tell Docker to forward port 600 on the host to port 600 in the container. Nothing's listening on that port, so you can't connect.
(3) If you docker run -p 600:1433, you'd tell Docker to forward port 600 on the host to port 1433 in the container, where the server is listening, and I would expect this to work.

I set up Anzograph DB Free Edition in Docker Desktop on my Mac, and (per the commands below) ran it. But I can’t connect to the admin console.
docker pull cambridgesemantics/anzograph
docker run cambridgesemantics/anzograph
When I use the inspect feature in Docker Desktop’s Dashboard, all of the ports for the running image are “not binded”. I would have expected to connect on port 5600 but that doesn’t work – not with localhost, not with 0.0.0.0, not with 127.0.0.1 …
Am I perhaps missing some pre-requisite? I allocated 8 GB of memory to Docker.
From the information you documented, what you are seeing is true as you have not documented in your command the specific ports.
What you entered was the following,
docker run cambridgesemantics/anzograph
What you should run to address this, which is documented on the download page for Anzograph, specifying the ports to install,
docker run -d -p 80:8080 -p 443:8443 --name=anzograph cambridgesemantics/anzograph:latest
AnzoGraph frontend binds to port 8443 (https) and 8080 (http),
AnzoGraph DB binds to port 5600 (gRPC DB management) and 5700 (gRPC DB query) inside the docker container.
Docker Desktop for MAC is mapping these container internal ports to ports on localhost. If you do not tell docker how to map those ports, it uses a random strategy to allocate those ports on localhost. In specifying the mapping
docker run -d -p 80:8080 -p 443:8443 -p 5600:5600 -p 5700:5700 --name=anzograph cambridgesemantics/anzograph:2.1.1-latest
you tell docker what localhost ports to use ( -p { localhost port } : { port inside of container} )
Many users new to docker struggle, when they use for example Kitematic, or similar UIs, that make it simple to deploy a running docker container, however they face complexities understanding and determining these random ports.
So if you are new to docker, and you do not want to use kubernetes yet, please use the command line to specify the localhost ports - it ends up being easier.
I've downloaded and ran this Docker image mcr.microsoft.com/mssql/server:
docker run -d -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Password!1" -p 1433:1433 --name sqlserver-test -d mcr.microsoft.com/mssql/server
up this point everything is OK.
Then I go to the SQL Server Management Studio and try to connect to localhost with user sa, but something is wrong because SSMS throws an exception that says something about network error.
Any ideas?
Try connecting to localhost, 1433 Also, confirm you don't have a real install of SQL Server on your machine trying to use port 1433. You might need to map port 1434->1433 and then connect with localhost, 1434
I am attempting to create a Docker container from a SQL Server image using the following Docker command:
docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=p#$$w0rd!" -p 1433:1433 --name sql2 -d microsoft/mssql-server-linux:2017-latest
However, the running the command tells me that port 1433 is already in use:
docker: Error response from daemon: driver failed programming external
connectivity on endpoint sql2
(6cfcd552054d9e9d62d1e9ec1c11a6c5051e6912cc6658e12b0bc5e992c30cfd): Error
starting userland proxy: Bind for 0.0.0.0:1433 failed: port is already allocated.
There are no other existing containers, and running the docker container ps -a command displays the container, but without a specified port.
Can anyone tell me why I am getting this error message and what can be done to fix it?

You probably have SQL Server installed that is using port 1433. You can
1) Use a different port
2) Shut down SQL Server service (using services.msc)
Following the documentation on the microsoft/mssql-server-linux page, it provides the following command to get a docker container running.
docker run -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=Test!234' -p 1433:1433 -d --name sqllinux microsoft/mssql-server-linux
This works fine and I'm able to open up SSMS and connect to localhost with the credentials:
username: sa
password: Test!234
What I wanted to do after that is to create a Dockerfile that will create the image that will do the same thing:
FROM microsoft/mssql-server-linux
ENV ACCEPT_EULA Y
ENV SA_PASSWORD Test!234
EXPOSE 1433 1433
I then ran docker build . -t sqltestfile followed by docker run sqltestfile.
The container seems to start just fine and through Kitematic I can see (what looks like to me) the same output as running the other image, but I'm not able to connect to this image through SSMS using localhost.
What needs to be changed about the Dockerfile to have it work the way I would expect (can connect to the container instance using SSMS through localhost)?
Any help would be greatly appreciated!
You still need to explicitly publish the port with -p.
From the docs:
The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime. You can specify whether the port listens on TCP or UDP, and the default is TCP if the protocol is not specified.
The EXPOSE instruction does not actually publish the port. It functions as a type of documentation between the person who builds the image and the person who runs the container, about which ports are intended to be published. To actually publish the port when running the container, use the -p flag on docker run to publish and map one or more ports, or the -P flag to publish all exposed ports and map them to to high-order ports.
I'm trying to setup SQLserver on my mac using Docker.
When I start it, it seems to be working, but when I try to connect with mssql, it crashes.
I have tried with localhost instead of 0.0.0.0, same result.

d'oh.... the problem was with the password for sql server. It need to be a strong pw.
thanks for your help! and happy new year :)
