export/import realms - illegal json format? - keycloak-user

Tuesday, 12 November 2019

Hi,

I'm using Keycloak docker 7.01 to export all my realms into a json file realms.json.
Then, I take the json file and try to import in another container.
The json looks like:

[ {
    "id" : "tenant1",
    "realm" : "tenant1",
    ....
},
{
    "id" : "tenant2",
    "realm" : "tenant2",
   ....
} ]

However, after I run the import, I get an error about the json format. I checked the json
with an online validator, and it seems to be valid.
Is that a bug? Is there any way to reformat the json so it will work?

When I export/import a single tenant, I don't get the error.

Here is my export command:

docker exec keycloak /opt/jboss/keycloak/bin/standalone.sh \
-Djboss.socket.binding.port-offset=100 -Dkeycloak.migration.action=export \
-Dkeycloak.migration.provider=singleFile \
-Dkeycloak.migration.usersExportStrategy=REALM_FILE \
-Dkeycloak.migration.file=/tmp/vol/realms.json

Here is my import command:

sudo docker run -d -p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin -e
KEYCLOAK_IMPORT=/tmp/vol/realms.json -v /home/caadmin/keycloak:/tmp/vol  --name keycloak
jboss/keycloak

This is the error I get:
