I m trying to pull images in my pipeline in a dynamic way. I have a file call "images.txt" that contain:(cat images.txt would return)
cat images.txt
cassadra
python
neo4j
the way to pull a image in azure pipeline is:
that code work but its not dynamic
steps:
- bash: |
y='python:3.8-slim' #I m using tha as var but would work without that
docker pull ${y}
displayName: "Docker pull"
But when I try to do it dynamically it doesnt work anymore:
That code work im my local laptop but not in azure pipelines and in theory both should work
#!/bin/bash
filename='images.txt'
n=1
while read line; do
# reading each line
eval docker pull "$line"
n=$((n+1))
done < $filename
in Azure pipelines look like this:
- bash: |
#x='python:3.8-slim'
filename='images.txt'
n=1
while read line; do
echo "pulling image"
echo ${line}
n=$((n+1))
docker pull ${line}
done < $filename
but I m reciving the whole time that error: so
invalid reference format
it was my understanding that everything that worked on linux would work on Azure Pipelines(inside bash) what I am not taking into account ?
Thanks in advance Enrique
