mvn clean install -P docker
```

### Nexus container image
```
nexus3.onap.org:10001/onap/org.onap.oom.platform.cert-service.oom-truststore-merger:latest
```

### Running application as standalone docker container

Exemplary config.env file with necessary envs
```
TRUSTSTORES_PATHS=/var/certs/truststore.jks:/var/certs/truststore.pem
TRUSTSTORES_PASSWORDS_PATHS=/var/certs/truststoreJks.pass:
```
TRUSTSTORES_PATHS env indicates paths (separated by ":") where truststores files are located.

TRUSTSTORES_PASSWORDS_PATHS env indicates paths (separated by ":") where files with passwords to truststores are located.
PEM is not protected by password so its value should be empty

Execute below command in order to run app as docker container
```
docker run \
    --name oom-truststore-merger \
    --env-file ./config.env \
    --mount type=bind,src=<src_path>,dst=/var/certs \
onap/org.onap.oom.platform.cert-service.oom-truststore-merger:latest
```
Before run replace <src_path> with absolute path where you located truststores to merge (eg. /certs/resources/)

Output from merger (when pointed more than one truststore to merge in TRUSTSTORES_PATHS env) success execution should be:
1. Created backup file (with .bak ext) of first truststore pointed in TRUSTSTORES_PATHS env
2. First truststore pointed in TRUSTSTORES_PATHS env contains merged certificates from all truststores mentioned in TRUSTSTORES_PATHS env

Remove docker container:
```
docker rm oom-truststore-merger
```
