+# ansible-builder
+[AWX](https://www.ansible.com/products/awx-project/) is used in smardigo setup do execute several playbooks due to user interaction within smardigo product. To finish ansible runs successfully we have to make sure every ansible dependency(ansible collection/role or pip package) is installed. therefore ansible-builder gave us the opportunity to configure the needed environment to exec plays successfully. 
+
+before every git-merge depending on changes concerning new ansible collections/roles and/or new pip-packages, please run the following:
+
+    cd ansible-builder/
+    ansible-builder build --tag awx-custom-ee:latest --container-runtime docker
+
+
+
+hopefully it will result in e.g.:
+
+    cd ansible-builder/
+    ATTENTION: to get more information plz set --verbosity 3	
+    ansible-builder build --tag awx-custom-ee:latest --container-runtime docker
+    Running command:
+      docker build -f context/Dockerfile -t awx-custom-ee:latest context
+    
+    Complete! The build context can be found at: /home/friedrich/sandbox/netgo_stuff/hetzner-ansible/ansible-builder/context
+    
+    real	2m56,131s
+    user	0m0,208s
+    sys	0m0,102s`
+ 
+you can start the docker container locally with e.g. :
+    docker run -it --rm --mount type=bind,source="$(pwd)"/,target=/gitrepo/   awx-custom-ee:latest /bin/bash
+
+
+after it, you are able to exec some ansbible-runs like:
+(please solve dependencies before starting to docker container)
+    cd /gitrepo
+    ansible-playbook -i stage-digitalocean external_monitoring.yml --ask-vault-password -u root --private-key sshkey_pw_less 
+    
+    export HETZNER_LABEL_SELECTOR='stage=dev'
+    ansible-playbook -i stage-netgo-hcloud.yml -l redis smardigo.yml --ask-vault-password  -u root --private-key sshkey_pw_less
+  
+
+if everything works fine, plz push the created docker container with:
+
+    docker login dev-docker-registry-01.smardigo.digital
+    docker tag XXXXXXXX dev-docker-registry-01.smardigo.digital/awx/awx-custom-ee:latest
+    docker push dev-docker-registry-01.smardigo.digital/awx/awx-custom-ee
