I'm trying to launch SQL Server for a technical test on my Macbook. Docker seemed to be best solution.
Tried using instructions from https://database.guide/how-to-install-sql-server-on-an-m1-mac-arm64/
Installed Docker okay.
Then tried to use:
sudo docker run --cap-add SYS_PTRACE -e 'ACCEPT_EULA=1' -e 'MSSQL_SA_PASSWORD=bigStrongPwd' -p 1433:1433 --name sqledge -d mcr.microsoft.com/azure-sql-edge
But when I tried to test the Docker using:
docker ps
The result was this:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
What's gone wrong?

I was following this guide on customizing MySQL databases in Docker, and ran this command multiple times after making tweaks to the mounted sql files:
docker run -d -p 3306:3306 --name my-mysql -v /Users/pneedham/dev/docker-testing/sql-scripts:/docker-entrypoint-initdb.d/ -e MYSQL_ROOT_PASSWORD=supersecret -e MYSQL_DATABASE=company mysql
On all subsequent executions of that command, I would see an error like this:
docker: Error response from daemon: Conflict. The container name "/my-mysql" is already in use by container "9dc103de93b7ad0166bb359645c12d49e0aa4a3f2330b5980e455cec24843663". You have to remove (or rename) that container to be able to reuse that name.
See 'docker run --help'.
What I'd like to know is whether that docker run command can be modified to auto-kill the previous container (if it exists)? Or if there is a different command that has the same desired result.
If I were to create a shell script to do that for me, I'd first run docker ps -aqf "name=mysql" and if there is any output, use that resulting container ID by running docker rm -f $containerID. And then run the original command.
docker run command has a --rm arguments that deletes the container after the run is completed. see the docs . So, just change your command to
docker run --rm -d -p 3306:3306 --name my-mysql -v /Users/pneedham/dev/docker-testing/sql-scripts:/docker-entrypoint-initdb.d/ -e MYSQL_ROOT_PASSWORD=supersecret -e MYSQL_DATABASE=company mysql
So, as the title states, I'm a docker newbie.
I downloaded and installed the archlinux/base container which seems to work great so far. I've setup a few things, and installed some packages (including xeyes) and I now would like to launch xeyes. For that I found out the CONTAINER ID by running docker ps and then used that ID in my exec command which looks now like:
$ docker exec -it -e DISPLAY=$DISPLAY 4cae1ff56eb1 xeyes
Error: Can't open display: :0
Why does it still not work though? Also, how can I stop my running instance without losing its configured state? Previously I have exited the container and all my configuration and software installations were gone when I restarted it. That was not desired. How do I handle this correctly?
Concerning the X Display you need to share the xserver socket (note: docker can't bind mount a volume during an exec) and set the $DISPLAY (example Dockerfile):
FROM archlinux/base
RUN pacman -Syyu --noconfirm xorg-xeyes
ENTRYPOINT ["xeyes"]
Build the docker image: docker build --rm --network host -t so:57733715 .
Run the docker container: docker run --rm -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY so:57733715
Note: in case of No protocol specified errors you could disable host checking with xhost + but there is a warning to that (man xhost for additional information).
I am using Postgres image and past broker image in my docker machine for setting up pact broker.
here are 4 steps that have mentioned :
1.$ docker run --name pactbroker-db -e POSTGRES_PASSWORD=ThePostgresPassword -e POSTGRES_USER=admin -e PGDATA=/var/lib/postgresql/data/pgdata -v /var/lib/postgresql/data:/var/lib/postgresql/data -d postgres
2.$ docker run -it --link pactbroker-db:postgres --rm postgres sh -c 'exec psql -h "$POSTGRES_PORT_5432_TCP_ADDR" -p "$POSTGRES_PORT_5432_TCP_PORT" -U admin'
3.
CREATE USER pactbrokeruser WITH PASSWORD 'TheUserPassword';
CREATE DATABASE pactbroker WITH OWNER pactbrokeruser;
GRANT ALL PRIVILEGES ON DATABASE pactbroker TO pactbrokeruser;
4. docker run --name pactbroker --link pactbroker-db:postgres -e PACT_BROKER_DATABASE_USERNAME=pactbrokeruser -e PACT_BROKER_DATABASE_PASSWORD=TheUserPassword -e PACT_BROKER_DATABASE_HOST=postgres -e PACT_BROKER_DATABASE_NAME=pactbroker -d -p 80:80 dius/pact_broker
after running this 4 command when I am opening Hal browser in my local system it is working pretty fine. Now I am stopping 2 docker containers pactbroker-db and pactbroker and stopping docker machine.
After sometime I am restarting docker machine and starting the containers by
$docker start pactbroker-db and $docker start pactbroker .
containers are getting started but when opening HAL browser I am getting the error "We're sorry, but something went wrong." screenshot attached.
Is there something wrong when I am starting the docker 2nd time?enter image description here
This has been resolved by using container given in https://github.com/DiUS/pact_broker-docker and using proper environment variables in docker-compose.yml of this project.
I've used docker to install couchbase on my ubuntu machine using (https://hub.docker.com/r/couchbase/server/). The docker run query is as follows:
docker run -d --name db -p 8091-8094:8091-8094 -p 11210:11210 -v /home/dockercontent/couchbase:/opt/couchbase/var couchbase
Everything works perfectly fine. My application connects, I'm able to insert/update and query the couchbase. Now, I'm looking to debug a situation wherein the couchbase is on my co-developers machine who also has the same installation i.e., couchbase on docker using the above link. For achieving this, I wanted to run cbbackup on his installation. To achieve this, I run the following command which is a variation of the above link:
bash -c "clear && docker exec -it couch-db sh"
Can anyone please help me with the location of /opt/couchbase/bin in this setup? I believe this is where I can get access to "cbbackup", "cbrestore" and "cbtransfer" which I can then use to backup and restore data from my colleague's machine.
Thanks,
Abhi.
When you run the command
docker run -d --name db -p 8091-8094:8091-8094 -p 11210:11210 -v /home/dockercontent/couchbase:/opt/couchbase/var couchbase
you're pulling a docker image and spawning a docker container.
Please read more about Docker and containerization.
In order to run cbbackup you need to log into your docker container.
Follow these steps:
Retrieve the container-id:
$ docker ps -a
Look for the CONTAINER ID for IMAGE NAME=couchbase
Login to the container using the command:
$ docker exec -it <container-id> bash
Go to the directory : /opt/couchbase/bin using:
$ cd /opt/couchbase/bin
You'll find cbbackup binary in this directory.
I ran the following command in docker:
sudo docker run --name my_mysql -e MYSQL_ROOT_PASSWORD=mysecretpassword -d mysql
When i actually wanted to run the following:
sudo docker run --name my_mysql -e MYSQL_ROOT_PASSWORD=mysecretpassword --volumes-from mydatastore -d mysql
Now after i ran the command(the 1st command) , the only way i could stop it was to close the terminal, soi closed it and then opened the terminal again and ran the second command, I.E.
sudo docker run --name my_mysql -e MYSQL_ROOT_PASSWORD=mysecretpassword --volumes-from mydatastore -d mysql
I get the following message:
"another repository already pulling"(or something similar to this error message ... i just messed up all my docker commands and now i can't seem to re-create this error) , How can i solve this issue ?
Either wait, or restart the docker daemon (probably service docker restart).
