AWS Codebuild, run builds in parallel
0
Hi,
I am using this config in a buildspec, but builds are still run sequentially:
version: 0.2
phases:
pre_build:
commands:
- pwd
- ls -la
build:
commands:
- echo "hi world" && sleep 50
- echo "hey" && sleep 10
- echo "hey" && sleep 20
batch:
fast-fail: true
build-list:
- identifier: build1
- identifier: build2
- identifier: build3
What have I missed?
Thank you

Hi,
Batch cannot be defined in the build section. You might see something like this in the build logs
In the section BUILD
The following keys cannot be identified:
batch
You build spec needs to be like below (some env variables added to verify the build stages)
version: 0.2
batch:
fast-fail: true
build-list:
- identifier: build1
env:
variables:
STAGE: build1
- identifier: build2
env:
variables:
STAGE: build2
- identifier: build3
env:
variables:
STAGE: build3
phases:
pre_build:
commands:
- pwd
- ls -la
build:
commands:
- echo "hi world" && sleep 50
- echo "hey" && sleep 10
- echo "$STAGE" && sleep 20
- echo "$AWS_DEFAULT_REGION"
Also you need to setup the batch configuration details for the build project and / or enable concurrency as well ( I could not verify the concurrency part). You would then have the details shown in the Batch history tab

OK, I found an answer. I need to use build matrix instead of build list. Then every echo will be running in parallel.

In this case I will have 3 batches, that will run the same commands: - echo "hi world" && sleep 50 - echo "hey" && sleep 10 - echo "$STAGE" && sleep 20 - echo "$AWS_DEFAULT_REGION"
But I want, that one batch run - echo "hey" && sleep 10 and another run - echo "$STAGE" && sleep 20 at the same time, is it possible?
About concurrency part, I need to contact AWS support to increase the concurrent build limit, as default is 1.
Also, batch can be defined in the build section. I just use my first script above and I don't choose any batch configuration detail. There are no errors, but commands are running in sequence.
i dont think batch is designed for that. If you have mutiple environments / environment variables for which you need to run identical commands you use batch.
It wont throw up any errors but within the build logs you would see the log snippet i mentioned in the previous comment. That's what i got in my logs. It's essentially ignoring the batch section.

I have a few docker build commands in my buildspec. I have docker build -t 1 and docker build -t 2. My goal was to run them in parallel just to reduce the build time. Is that possible?
