How to change the setting of apache superset from sqlite to MySQL - apache-superset

Can anyone provide a steps to Change the setting of apache superset from sqlite to MySQL?
I have create superset_config.py to override the configuration
after adding the property i am able to enabled swagger url
I have added SQLALCHEMY_DATABASE_URI = 'mysql://root:xxxxxx#127.0.0.1:3306/superset' property in superset_config.py file
but still it is connecting with SQLlite.

I wrote article that can help you.
I had problem using docker compose and native installation . Port is closed can be due to networking problem or problem with packages. Host.docker.internal doesn’t worked for me on Ubuntu 22. I would like to recommend to not follow official doc and use better approach with single docker image to start. Instead of running 5 containers by compose, run everything in one. Use official docker image, here image. Than modify docker file as follows to install custom db driver:
FROM apache/superset
USER root
RUN pip install mysqlclient
RUN pip install sqlalchemy-redshift
USER superset
Second step is to build new image based on docker file description. To avoid networking problems start both containers on same network (superset, your db) easier is to use host network. I used this on Google cloud example as follow:
docker run -d --network host --name superset supers
The same command to start container with your database. —network host. This solved my problems. More about in whole step to step tutorial: medium or here blog

How to apply Superset Migrations when running in docker mode?

Currently I'm running Superset in Docker mode. No native installation. The metadata database is an external(non-docker) Postgres DB which has lots of Dashboards, Charts etc.
Current installation is running on git tag 1.0.0. I want to upgrade to v1.1.0. I can do this by switching the repo to git tag 1.1.0 and restarting docker containers.
However as per UPDATING.md notes, v1.1.0 has a DB migration .
In native installation, the way to migrate DB is superset db upgrade
What's the proper method to apply these migration scripts to an existing external database in docker installation?
Lauch you stack if done with compose it will run automaticly the db upgrade command.
if not docker exec -it <supersetcontainerID> /bin/bash
Just ensure to have the correct sqlalchemy chain on the superset config file.
And then fire the superset db upgrade
You're done.
First, chekout your container id ,then use below command to backup superset.db
docker cp 1263b3cdf7e7:/root/.superset/superset.db
Then after the upgrade,you can just simple cp and replace superset.db back into your new version

docker context create ecs myecs - requires exactly one argument

I'm trying to create a Docker context that will automatically integrate with AWS's ECS.
I'm following this tutorial
The author just does:
docker context create ecs myecs and gets a "pick an integration" prompt, whereas I get an error saying it needs exactly 1 argument.
docker context create" requires exactly 1 argument.
See 'docker context create --help'.
Usage: docker context create [OPTIONS] CONTEXT
Create a context
You need to install the Docker Compose CLI preview
The below curl is from here: Docker docs
curl -L https://raw.githubusercontent.com/docker/compose-cli/main/scripts/install/install_linux.sh | sh
sudo docker context create ecs myecs
It didn't work without sudo for me for some reason.
After the script finished I had some weird errors:
cp: cannot stat '/tmp/tmp.d4QjhW8T6k/docker-compose': No such file or directory and docker context create ecs myecs didn't work at first, but once I tried with sudo it worked fine.
EDIT: . ~/.zshrc (or just close your terminal and open a new one) made it possible for me to run docker context create ecs myecs without sudo.
Author of the blog/tutorial here. It looks like you don't have the pre-requsite installed. In the blog I call out the pre-req in pieces like this.
....In July, Docker released a beta for Docker Desktop that embedded these functionalities and, on September 15th, Docker released an updated experience in their Docker Desktop stable channel....
and then
...For now the only thing you need is Docker Desktop and an AWS account. For this test , I am using Docker Desktop (stable) version 2.5.0.1....
and finally
The core of this integration is built around a new tool dubbed Compose CLI (this is not to be confused with the original docker-compose CLI). This new CLI surfaces to the user as new functionalities in the docker command. While in Docker Desktop all this plumbing is completely hidden and available out of the box, if you are using a Linux machine you can set it up using either a script or a manual install. This new CLI is, essentially, a new version of the docker binary.
Eager to understand more how we could make it more clear / front and center that there were stuff to install and/or minimum software versions you had to use.
Thanks for trying it out!
If you're on Linux and you're running the docker context create ecs myecscontext command from the docs then try enabling experimental features in docker:
Edit /etc/docker/daemon.json
Set contents to
{
"experimental": true
}
Restart docker service sudo systemctl restart docker
Exit your terminal and open a new one so that the changes take effect.

I had same issue but after installing Docker Desktop version problem resolved.
Server side version doesn't have such kind of functionality.

Running postgres 9.5 and django in one container for CI (Bamboo)

I am trying to configure a CI job on Bamboo for a Django app, the tests to be run rely on a database (postgres 9.5). It seems that a prudent way to go about is it run the whole test in a docker container, as I do not control the agent environment so I cannot install Postgres there.
Most guides I found recommend running postgres and django in two separate containers and using docker-compose to easily manage them. In this scenario each docker image runs just one service, started with CMD. In Bamboo I cannot use docker-compose however, I need to use just one image, so I am trying to get Postgres and Django to run nicely together in one container but with little success so far.
My problem is that I see no easy way to start Postgres as a service inside docker but NOT as a docker CMD command, official postgre image uses an entrypoint.sh approach, also described in the official docker docs
But it is not clear to me how to implement that. I would appreciate your help!
Well, basically you would start postgres as a background process in the docker-entrypoint shell script that does otherwise start your django application.
The only trick here is that you need to put a 'trap' command in it so that you can send a shutdown/kill to the background process when your master process stops.
Although I have done that a thousand times, I know that it is a good source for programming errors. In general I do just use my docker-systemctl-replacement which takes care of running multiple applications as services, just as if the container is a virtual machine hosting multiple applications.
Your only other option is to add in a startup script in your Dockerfile, or kick it off as part of your docker run ... commands. We don't generally use the "Docker" tasks, as I find them ... distasteful (also why I usually just fall back to running a "Script" task, and directly calling docker run in that script task)
Anyway, you'd have to have your Docker container execute a script that would:
Start up Postgres (like a sudo systemctl start postgresql)
Execute your tests.
Your Dockerfile will have to install Postgresql and do some minor setup work I imagine (like create relevant users and databases with the proper owner). Since we're all good citizens, we remember to never run your containers as root, right?
Note - you can always hack around getting two containers to talk to each other without using docker-compose. It's a bit less convenient, but you could do something like:
docker run --detach --cidfile=db_cidfile --name ci_db postgresql_image
...
docker run --link ci_db testing_image
Make sure that you EXPOSE the right ports on the postgresql image to the testing_image container.
EDIT: I'm looking more at my specific case - we just install Postgresql into a base CentOS host rather than use the postgresql default image (using yum install http://yum.postgresql.org/..../pgdg-centos...rpm and then just install postgresql-server and postgresql-contrib packages from there). There is a CMD [ "/usr/pgsql-ver/bin/postgres", "-D", "/var/lib/pgsql/ver/data"] in our Dockerfile, too. We don't do anything fancy with the docker container, though. NOTE: we don't use this in production at all, this is strictly for local and CI testing.

Deploy Django app with Docker

I'm attempting to deploy a Django app via docker, first locally, and then to a cloud server. I could not find an answer to my initial question before I attempt this: if I run docker-machine create, I'm guessing this should be run from within my virtualenv, right?
This would then grab all of my specific app dependencies, and begin to build certificates to throw in the container? If not, please explain otherwise..
Yes you are correct.
I will try to help you by my experience, if you wanna deploy django apps via docker.
First you need to setup docker machine in your local machine. Please see the
instruction. By default driver that will be used is --driver
virtualbox default.
List what kind of specifics dependencies images of your apps. Ex:
you need nginx, postgres, uwsgi, or you need to fetch an image then
modified that image you can use dockerfile (its the best practice
for you).
I suggested you to use docker-compose. Really its make our project
pretty easy to manage. You have to define all images that you need
for your app in docker-compose file Please read this reference.
After you finished develop your app then you want to deploy in production server (cloud) you just need to copy all your project then running your docker-compose. All images dependencies will be automatically pulled in the cloud.
As a reference, you can see this project (this is an open source project that I developed.) On that project, I use make file to manage docker-compose command and it make easy to manage.
An example of dockerfile
An example of docker-compose.yml
An example of Makefile
Hope this will help you.

Unable to setup Django in production on EC2 instance running Ubuntu 14.04

I have set up an EC2 instance with Ubuntu and able to login via ssh.
Now I have installed Apache, MySQL (worked fine) and Django also tried to configure it to run with apache. I have tried doing so with mod-wsgi but it still shows a apache default page instead of django (Congratulation ! It works) page. Can someone please provide me instructions for how to setup all this after login into EC2 via SSH.
Here is a tutorial provided by Django.
You need to make sure the apache config file is in /etc/apache2/sites-enabled/ or wherever your apache configuration files rest.
Another silly problem and this might be your issue is whenever I start a new instance of EC2 there is always a config called "000-default" already in the apache sites-enabled. This needs to be DELETED or DISABLED for apache to read from your config instead.
Hopefully this helps!
For a example check the Step 2 of this link. yum + git + pip + python requirements
