Hi!
Last week at Sage Days 100 I learned how to put the code for my group
cohomology spkg on github and got an introduction on using travis-ci.
However, it seems that I need more help/pointers, in particular on docker.
The things that I want travis-ci to do are:
- Install dependencies of my code into a docker container. I guess that
goes to the "before_install" section of my .travis.yml file. So, it
should be pulling the latest sagemath-dev docker image, creating a
container and sending the commands "sage -i meataxe" and "sage -b" to
the container.
- Install the package itself. I guess that goes to the "install"
section. It involves opening a sage shell, installing some C library
with configure/make/make install, and install some Python/cython code
with "pip install .".
- Run some tests; I guess that goes to the "script" section.
My problems:
How to keep a docker container running? Currently, after executing a
command, the docker container simply exits. It was suggested to me at
the workshop to put all commands used to install and test my software
into a single shell script and execute that (which means to send only
a single command to the docker container), but it doesn't seem clean
to me (better separate before_install, install and script).
I tried to create and start a container and send commands using "docker
container exec". It did work sometimes, i.e., after some commands the
container stays up and running, but, e.g., it happened that after
"docker container exec sage -i meataxe" the container exited.
What is the recommendet way to proceed?
PS: I just tried some things again, getting a different error:
docker container create --name bla sagemath/sagemath-dev:latest
docker container start bla
docker container exec bla ls
docker container exec bla sage -i meataxe
results in an error in the last command, namely
make build/make/Makefile --stop

If you would like to try to build Sage anyway (to help porting),
export the variable 'SAGE_PORT' to something non-empty.

Makefile:39: recipe for target 'build/make/Makefile' failed
make[1]: Leaving directory '/home/sage/sage'

Why is that? "sage -i meataxe" did work before (at least with
"cocker container run ...")
Best regards,
Simon
