I'm trying to iterate over url entries in a file and use each file as an input for a crawler tool. It's result should be written to a file.
here is the gitlab-ci.yml file:
stages:
- test
test:
stage: test
tags:
- shell-docker
script:
- wget https://github.com/FaKeller/sireg/releases/download/v0.3.1/sireg-linux
- chmod 775 sireg-linux
- mkdir output
- ls -alF
- while read line; do
echo $line;
./sireg-linux exec --loader-sitemap-sitemap \"$line\" >> ./output/${line##*/}_out.txt;
done < sitemap-index
- ls -alF output
artifacts:
paths:
- output/*
expire_in: 1 hrs
and here is the sitemap-index file (only one entry):
http://example.com/sitemap.xml
both files are in the same directory. I expect a file sitemap.xml_out.txt to be written into the output folder(also the same directory). I am pretty sure the ./sireg-linux script does not execute because it usually takes few minutes to complete (tested locally).
the output of the stage looks like this:
2020-04-02 18:22:21 (4,26 MB/s) - »sireg-linux« saved [62566347/62566347]

update
tried to move all steps into a separate script but that did not work either.
update 2
forgot to add exec in the command:
./sireg-linux exec --loader-sitemap-sitemap \"$line\" >>
./output/${line##*/}_out.txt;
unfortunately it didn't help.
what can I do to make it working?
Try changing ./sireg-linux --loader-sitemap-sitemap \"$line\" to ./sireg-linux exec --loader-sitemap-sitemap "$line". Hope this helps!
EDIT: Also, it looks like the script doesn't enter the while loop at all. Maybe the file sitemap-index is empty or it has only one line without a newline at the end?
EDIT 2: The back-slashes in the command line are wrong. corrected my answer
You can of course painfully debug multi-line commands in YAML.
You can even use YAML multi-line strings:
How do I break a string over multiple lines?
https://gitlab.com/snippets/1717579
But I would just wrap code into a shell script, store it in the same GitLab repo, and just call it in .gitlab-ci.yml.
This way you can run this script exactly the same way both locally and in CI, which is a best practice in Continuous Delivery.

If the prompt is anything to go by, we are logged in as root in the minimal reproduction. Thus, we have root privileges and can read and write all files (external link).
When I run a bash file inside its directory in ubuntu there isn't any problem
But when I try to run it by its directory I get the error:
sh: 0: Can't open /directory/file.sh
I followed this steps:
$ cat web/test.sh
#!/bin/bash
touch /tmp/testweb
echo "File has been created succesfully"
$ ls -la web/test.sh
-rwxr--r-- 1 test test 88 Dec 5 05:58 web/test.sh

I'm building a gitlab ci pipeline, and try to create a directory if it not exists.
Can anybody tell me what I'm doing wrong here?

I now just used mkdir -p and removed the test
you have something with aws name, which might be symbolic link, hard link, regular file, vs.
first delete or move that file to somewhere else then try again
you can try -e (returns true if file exists regardless of type).
My goal is to have Jenkins 2 execute alpha integration tests between an express js app and a postgres db. I am to spin up containerized resources locally and test successfully with bash scripts that employ docker-compose. The relevant bash script is scripts/docker/dockerRunTest.sh.
However, when I try to do the same thing via Jenkins, Jenkins claims that the initiating script is not found.
Jenkinsfile
stage('Alpha Integration Tests') {
agent {
docker {
image 'tmaier/docker-compose'
args '-u root -v /var/run/docker.sock:/var/run/docker.sock --network host'
}

sh 'ls -lah ./scripts/docker/'

The file clearly exists per the ls output. I have some hazy idea that there may be some conflict between how shell scripts and bash scripts work, but I cannot quite grasp the nuance in how Jenkins is not able to execute a script that clearly exists.

tmaier/docker-compose image doesn't have /bin/bash interpreter installed by default since latest tag is an alpine image [1, 2]. This can be confirmed by running:
$ docker run -it --rm tmaier/docker-compose bash
/usr/local/bin/docker-entrypoint.sh: exec: line 35: bash: not found
To get the script working, either install bash in the docker image using apk add bash or change the shebang to #!/bin/sh if the script can be run using ash shell (the default shell in busybox).

I have the similar issue but in my case, it is because the shell script file has EOL in Windows format (if you open the file in the terminal using vi, you will see each line ends with ^M)
I can fix this using Notepad++ Edit -> EOL Conversion -> Unix (LF)
I´m using lemonlatte / docker-webvirtmgr as base file, but the problem is that there are no ssh keys configured for the user www-data, so I wrote the following shell script:
#!/bin/sh
if [ ! -d "/var/local/webvirtmgr/nginxhome" ]; then
mkdir /var/local/webvirtmgr/nginxhome
chown -R www-data:www-data /var/local/webvirtmgr/nginxhome
usermod -d /var/local/webvirtmgr/nginxhome www-data
su - www-data -s /bin/bash -c "ssh-keygen -b 2048 -t rsa -f ~/.ssh/id_rsa -q -N ''"
su - www-data -s /bin/bash -c "touch /var/local/webvirtmgr/nginxhome/.ssh/config && echo -e 'StrictHostKeyChecking=no\nUserKnownHostsFile=/dev/null' >> /var/local/webvirtmgr/nginxhome/.ssh/config"
su - www-data -s /bin/bash -c "chmod 0600 ~/.ssh/config"
fi
After that I added the two statements to the dockerfile:
ADD setupssh.sh /webvirtmgr/setupssh.sh
RUN /bin/sh -c "/webvirtmgr/setupssh.sh"
I already tried CMD /webvirtmgr/setupssh.sh, RUN /webvirtmgr/setupssh.sh but with no success...
When I run the script inside the container by hand it is working fine.
What is wrong here?
greetings
UPDATE:
Here is the link to the repo of the maintainer: link
UPDATE 2:
The build of the dockerfile was successful and I put the statement between:
RUN apt-get -ys clean
<statements were here>
WORKDIR /
The directory /var/local/webvirtmgr is defined as a volume.
VOLUME /var/local/webvirtmgr
Therefore this directory is a mountpoint in the running container and what you have added to it gets overwritten.
You will have to use a different directory, then your script will work.
Here´s a Dockerfile to test it:
FROM lemonlatte/docker-webvirtmgr
RUN mkdir /var/local/webvirtmgr2
RUN touch /var/local/webvirtmgr2/t && touch /var/local/webvirtmgr/t
