Unable to connect to SQL Server Linux Docker conta

I'm quite new to Linux OS's so hope this isn't a stupid question!!

Software:
Windows 10 Pro
Docker for Windows (1.13.0-beta38 (9805))
SQL Server Management Studio v17.0 RC1

Issue: I'm trying to connect to my SQL Server Linux container using SSMS. It's not worked, so looking over the documentation it seems you need SQL Server Tools installed (bottom of page) on top of of the SQL Server Linux image.

I followed these instructions to install SQL Server Tools on Ubuntu (base image of SQL Server Linux Image)

Error: bash: curl: command not found

Steps to reproduce error:

Pull latest microsoft/sql-server-linux image
Run according to instructions: docker run -e 'ACCEPT_EULA=Y' -e SA_PASSWORD=yourStrong(!)Password' -p 1433:1433 -d microsoft/mssql-server-linux
Attach to container using: docker exec -it <container_id> /bin/bash
Attempt to import public repository GPG keys: curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

Thing's I've tried:

I've tried running apt-get install curl but all i get is E: Unable to locate package curl
Googling - to no end

First edit - Connecting via SSMS I've tried connecting to the container from SSMS using the following server names (I am using SQL authentication with the credentials specified during the docker run command):

localhost:1433
localhost\[container_name]
[container_ip_address]:1433

Solution (kind of)
OK so i got this working. But I'm not 100% sure what did the trick.
I used localhost as the server name (defaults to port 1433)
I also mounted a volume to the container as part of my docker-compose.yml file:

volumes: 
  - C:\local\volume\path:/var/opt/mssql

I had the same issue and the comment from Ed Harper resolved my issue:
