`1.1 Introduction` of is helpful.
Here, I will write about how to use PARI / GP with Docker.
You can enter the container with the option -it.
By adding gp as shown below, PARI / GP will be started immediately after the container is started.
docker run -it pascalmolin/parigp-small gp
There is also `pascalmolin / parigp-full```, but this time it is `small```.
PARI / GP starts as follows.
I'm trying to calculate 1 + 1.

To re-enter the container, first find the CONTAINER ID you want to boot.
docker ps -aDisplays a list, including containers that are stopped.
docker ps -a
The list is displayed as shown below.
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Restart the container.
docker restart 1831fe3cb55f
Enter the container.
docker exec -it 1831fe3cb55f sh
Go to the tmp directory and try creating a file there.
/ # cd tmp
I created the following test.gp.
/tmp # cat test.gp
forprime(p = 1, 20, write("output.txt", p))
Start PARI / GP with the gp command as shown below.
/tmp # gp
Run the file.
? \r test.gp
Stop PARI / GP and take a look at the created output.txt.
/tmp # cat output.txt
