I've pulled a database image using docker and set the needed database url and credentials in my context.xml file. However, I get an access denied error when starting Tomcat. So I would like to connect to this Docker container with the help of cmd.
We suppose that your container is running.
So, use :
docker exec -t -i CONTAINER_NAME /bin/sh

I've pulled latest SQL Server docker image
docker pull mcr.microsoft.com/mssql/server
Then started with port 1400.
(I'm not using default port 1434 because I've a local instance of SQLServer running outside of docker which my SSMS can quickly connect)
docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=pa$$word#123" -e "MSSQL_PID=Express" --name "SQLServer" -p 1400:1400 -d mcr.microsoft.com/mssql/server
This is my container info
When I check the logs everything looks normal. But when I try to connect from SSMS, I'm getting the following error.
What could be the reason? I'm also planning to build a .NET Core application to connect to this docker image but now I've concerns regarding if it's some TLS version mismatch.
I found the solution. I need to specify the instance name in SSMS in order to connect to it
I'm running a localhost database through Docker on MAC. I have an assignment that requires me to hand in the .bak file along with the program I wrote. I'm using Azure Data Studio as DBMS. I can't find these anywhere and I've tried to google the matter but it doesn't seem as a common issue for other mac users.
How do i access these from Finder? Or is there another way to do this?
Accessing Docker Container File system from Mac OS host through this tutorial.
To access the file system of a particular Container, first, let us get the Container ID using the inspect command on the Docker Host.
docker inspect --format <Container Name>
Use the Alpine Docker image and mount your Host file system to the container
docker run --rm -it -v /:/vm-root alpine:edge sh
We need the ID of this container. So, you could combine the step 1 and 2 with the following
docker run --rm -it -e CONTAINER_ID=$(docker inspect --format <Container Name>) -v /:/vm-root alpine:edge sh
Now we have the CONTAINER_ID set as an environment variable in the alpine container.
Once you are in the alpine container, you can visit the following directory
cd /vm-root/var/lib/docker
Inside this directory, you will be able to access all the familiar files that you are used to when administering Docker
Now, we need to find the mount-id for the selected container to access the file system directories. We will use the CONTAINER_ID environment variable obtained in step 2. I have AUFS as my file system driver for the this example. To do that, use the following command.
MOUNT_ID=$(cat /vm-root/var/lib/docker/image/aufs/layerdb/mounts/$CONTAINER_ID/mount-id)
The above step will give you the mount-id. Now you can access the file system of the container under mnt directory with the mount-id
ls -ltr /vm-root/var/lib/docker/aufs/mnt/$MOUNT_ID
i’m trying to connect to a postgre database which is inside a docker container. I´m creating the docker container with following command:
docker run --name prodcoc -p 5432:5432 -e POSTGRES_USER=testuser -e POSTGRES_PASSWORD=test -e POSTGRES_DB=testDB postgres
After the container is running I want to connect to the created database with the created user, but that seems not possible. Why can't I connect to the database which I'm creating with the enviroment variables?
The solution for my problem was to uninstall the local PostgreSql instance. I don´t know why I installed it but removing it solved my problem.
In windows this can be done in the Settings.
I installed oracle db version 12c in my docker environment.
I used the following command:
docker run -d --name oracle -p 8080:8080 -p 1521:1521 quay.io/maksymbilenko/oracle-12c
I connected to the DB and everything went well but I wanted to enable unified audit.
In order to do that, at first you must shutdown the Database and in all the instructions that I found it says to use sqlplus as following:
sqlplus / as sysoper
SQL> shutdown immediate
SQL> exit
I connected successfully to the DB using the next command:
docker exec -it oracle "bash"
and then I ran the sqlplus command and I received "command not found"
[root#f30cc670f85f /]# sqlplus / as sysoper
bash: sqlplus: command not found
Am I doing it wrong?
What should I do in order to have sqlplus on my oracle DB?
I looked for it and didn't find anything that helped me.
I have mac if its relevant
I think that Docker image is just the database and enough of the OS to run the database. I don't think it includes client software such as SQL*Plus.
You need to have SQL*Plus installed on your Mac. If you haven't already, download the Oracle Instant Client for MacOS including the SQL*Plus extension. Or why not treat yourself and install the new-fangled sqlCL tool? It is easier to install and has all the SQL*Plus capabilities and a whole bunch more features. Find it here.
Whatever client you choose, once it's installed on your Mac you run it like any other app: when prompted for connection you give the string Maksym provides:
system/oracle#//localhost:1521/xe
If you need to connect as sys that would look like this:
sys/oracle#//localhost:1521/xe as sysdba
Sourcing the .bashrc should work to connect to sqlplus as sysdba.
docker-compose exec db bash -c "source /home/oracle/.bashrc; sqlplus sys/Oradoc_db1#ORCLCDB as sysdba;"
with this, you enter the image:
docker exec -it oracle /bin/bash
after that, you can use:
sqlplus sys as sysdba
When using the docker image store/oracle/database-enterprise:12.2.0.1-slim sqlplus and sqlldr tools are only available after the container has started.
You can't do the following in a Dockerfile:
RUN sqlplus sys/password AS SYSDBA #create_database.sql
The container images can be configured to run scripts after setup and on startup. Currently sh and sql extensions are supported.
In your Dockerfile, copy the SQL script into the startup directory:
COPY create_database.sql /opt/oracle/scripts/setup/01_create_database.sql
The database will be created on first startup of the container.
I don't have any experience with docker, but it looks for all the world like you are getting to a bash environment, so there we are on solid ground. The returned error ("bash: sqlplus: command not found") simply means that the executable (sqlplus) was not found in any directory listed in your PATH environment variable, as it exists within your shell environment. You actually need to set three variables: ORACLE_SID needs to be set to the value of your database name. ORACLE_HOME needs to be set to the value of the directory where your oracle binaries are installed. And PATH needs to have $ORACLE_HOME/bin added to it:
export PATH=$ORACLE_HOME/bin:$PATH
Obviously, since you are using the value of ORACLE_HOME in setting PATH, ORACLE_HOME needs to be set first.
For Windows OS:
Type docker ps in command line to show running containers and check container id.
Type docker exec -it container_id //bin/bash
Login via sqlplus command
Or the simplest way
docker exec -it container_id bash -c "source /home/oracle/.bashrc; sqlplus sys/Oradoc_db1#ORCLCDB as sysdba;"

I install docker container on mac(OS X) and install Microsoft SQL 2017 image file on docker.So, I try to connect docker with Azure Data Studio but didn't connect it. Can I connect docker with Azure Data Studio and How to configure it? Please help me, thank a lot.
Use 127.0.0.1,1433 instead of 127.0.0.1:1433
This syntax is what my ASP.NET Core app uses as syntax so I figured MS liked that format for connection strings and such.
This worked for me. Hope it helps.
I was able to run SQL server on MAC using Docker by running it along with the Azure Data Studio.
In order to connect to a server, you need to go to preferences of your Docker settings and increase the Memory allocation from the default of 2GB to minimum 4GB (as SQL server needs min 3.25GB space). Save and restart the docker.
Once restarted, all you need to do is pull the docker image of the sql server and download it. this can be done by below commands on your terminal . FYI, I am using bash commands below:
Command 1:
sudo docker pull mcr.microsoft.com/mssql/server:2017-latest
This will pull the latest vesion docker image and download. Once done, you need to set your SQL authentication on the server for your database. Follow below commands:
Command 2:
sudo docker run -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=<SetYourPasswordHere>' \
-p 1433:1433 --name sql1 \
-d mcr.microsoft.com/mssql/server:2017-latest
This sets your password and uses the port 1433 for SQL server (which is the default port). To confirm if the image has been created and the SQL server is running on docker, execute the below command to check log(s).
Command 3:
docker ps
To check all instances in your history of dockers( i.e. if you already had dockers installed before you are attempting this SQL connection/execution), run the below command and it will give you all the logs of all instances you have created
Command 4:
docker ps -a
or
docker ps -all
Once, you have completed above steps and see that the docker has created SQL instance, you need to go to Azure Data Studio and set the below credentials to access the server that you just created above using Docker.
Server: localhost
Authentication Type: SQL Authentication
Username: sa
Password: <Check Command 2 to see what you entered in the password where it says SetYourPasswordHere>
Hope this helps in your tryst with running SQL server on your MAC. All the Best!
You certainly can connect to a sql server image running in a docker container through azure data studio,
Based on the details mentioned in the question, I'm assuming that you have followed the steps on Microsoft docs for configuring sql server with docker,
The following command is needed to configure and run the SQL Server image docker container:
sudo docker run -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=your-strong-password’ -p 1433:1433 -d mcr.microsoft.com/mssql/server:2017-latest;
To quickly verify
check that the image is running by running:
docker ps -a
And checking the status column (with the correct instance name) to be 'UP',
Then launch Azure Data Studio and fill the connection details:
If you have followed all the default settings in setting up the image, this should work for you,
Hope this helps,
I hope first you have installed sql-cli(make sure you have node.js installed in your system),
Then connect to Mssql with command -> mssql -u -p
try to connect/create a database with docker first then connect from Azure Data Studio
