Docker Compose v1 uses the command
docker-compose. As of June 2023, support ends for Docker Compose v1.Docker Compose v2 uses the command
docker compose.If you are using Docker Compose v1 please adjust the commands accordingly. More information on Docker Compose can be found here.
Run one of the following commands to confirm that Docker Compose is installed:
Docker Compose v1:
docker-compose version
Docker Compose v2:
docker compose version
Example Output:
Docker Compose version v2.16.0
To ensure that Docker has the ability to pull and run container images run the following command:
docker run hello-world
Example Output:
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete
Digest: sha256:ffb13da98453e0f04d33a6eee5bb8e46ee50d08ebe17735fc0779d0349e889e9
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

In order to run PowerShell Universal, you can use the provided container image. The docker image is available on Docker Hub.
The prebuilt version supports both free & paid features of PowerShell Universal.
You can start the container by pulling the image and then running a container with the default port bound.
docker pull ironmansoftware/universal
docker run --name 'PSU' -it -p 5000:5000 ironmansoftware/universal
If port 5000 is unavailable on your host, this can be switched to another port.
e.g. Present on port 80
docker pull ironmansoftware/universal
docker run --name 'PSU' -it -p 80:5000 ironmansoftware/universal
The
docker run command will allow you to mount a volume for persistent storage. This needs to be mounted to the /root folder.Mount a volume on container in Windows
The following command mounts the folder
C:\docker\volumes\PSU to /root on your containerdocker pull ironmansoftware/universal
docker run --name 'PSU' -it -p 5000:5000 -v C:\docker\volumes\PSU:/root ironmansoftware/universal
Mount a volume on Container on Mac and Linux
The following command mounts the folder
/docker/volumes/PSU to /root on your containerdocker pull ironmansoftware/universal
docker run --name 'PSU' -it -p 5000:5000 -v /docker/volumes/PSU:/root ironmansoftware/universal
The following command removes a stopped container named
PSUdocker stop PSU
The following command stops a container named
PSUdocker rm PSU
The
--force flag can be used to remove a running containerdocker rm --force PSU
Docker Compose allows you to use a yaml text file to standardize your build and script the deployment (or build) or multiple containers.
The default name for any compose file is
docker-compose.yml it is recommended you use this as your compose filename.The following compose file will run a Powershell Universal container in Windows
version: "3.7"
services:
PSU:
container_name: PSU
image: ironmansoftware/universal:latest
ports:
- 5000:5000
restart: unless-stopped
environment:
- TZ=Europe/London
volumes:
- C:\docker\volumes\PSU:/root
The following compose file will run a Powershell Universal container on Mac's and Linux
version: "3.7"
services:

container_name: PSU

ports:

restart: unless-stopped
environment:

volumes:
- /docker/volumes/PSU:/root
Using a Terminal shell, or PowerShell for Windows. cd to the directory with your
docker-compose.yml script.Run the following command
docker compose up -d
Example Output:

Using a Terminal shell, or PowerShell for Windows. cd to the directory with your
docker-compose.yml script.Run the following command

You can add Environment variables into your Compose Scripts. Below is an example of:
- Setting a node name
- Adding SQL persistance
- Adding a SQL Connection String
version: "3.7"
services:
PSU:
container_name: PSU
image: ironmansoftware/universal:latest
ports:
- 5000:5000
restart: unless-stopped
environment:
- TZ=Europe/London
- Plugins__0=SQL
- Data__ConnectionString = "Data Source=ServerName; Initial Catalog=DatabaseName; User Id=UserName; Password=UserPassword;"
- NodeName=mynodename
volumes:
- /docker/volumes/PSU:/root
In some cases, you may wish to build more features, modify, or hardcode Environment Variables into your container.
For that, you will need to Create a
DockerfileNOTE: Dockerfiles' are case-sensitive and must start with a capital 'D'.
To create a Docker image that can persist the Universal data, you can create a dockerfile like the one below.
This Dockerfile exposes port 5000, creates a /data volume, sets configuration environment variables to store the Universal repository and database in the volume and then sets the Universal.Server as the entry point to the container.
FROM ironmansoftware/universal:latest
LABEL description="Universal - The ultimate platform for building web-based IT Tools"
EXPOSE 5000
VOLUME ["/home/data"]
ENV Data__RepositoryPath /home/data/Repository
ENV Data__ConnectionString /home/data/database.db
ENV UniversalDashboard__AssetsFolder /home/data/UniversalDashboard
ENV Logging__Path /home/data/logs/log.txt
ENTRYPOINT ["./Universal/Universal.Server"]
From the path your Dockerfile is hosted in run the following command:
docker build . --tag=universal-persistent
FROM ironmansoftware/universal:1.3.1-windowsservercore-1809
LABEL description="Universal - The ultimate platform for building web-based IT Tools"
EXPOSE 5000
VOLUME ["C:/data"]
ENV Data__RepositoryPath C:/data/Repository
ENV Data__ConnectionString C:/data/database.db
ENV UniversalDashboard__AssetsFolder C:/data/UniversalDashboard
ENV Logging__Path C:/data/logs/log.txt
ENTRYPOINT ["C:/ProgramData/Universal/Universal.Server.exe"]
You can run a build with the build command.
docker build . --tag=universal-persistent
You can start the docker container with the run command and make sure to specify the volume to mount.
docker run -it --name powershelluniversal --mount source=psudata,target=/home/data --rm -d -p 5000:5000/tcp universal-persistent:latest
To use SQL persistence, you can define the plugin and connection string as follows.
ENV Data__ConnectionString=Data Source=ServerName; Initial Catalog=DatabaseName; Integrated Security=SSPI;
ENV Plugins:0=SQL
To properly support time zones on Linux when scheduling jobs, you will need to include the
tzdata package in your dockerfile along with an environment variable that specifies the server time zone.ENV TZ Europe/Amsterdam
RUN apt-get install -y tzdata
We publish the following tags to Docker Hub.
