Hello guys, I am new in Dgraph
I want to try tutorial running dgraph in docker with this yaml https://github.com/dgraph-io/dgraph/blob/master/contrib/config/docker/docker-compose-ha.yml
Simple as that - i just run
docker-compose up -d
But container alpha not running with error :
Cannot acquire directory lock on "p". Another process is using this Badger database. error: resource temporarily unavailable
Error while creating badger KV posting store
any suggestions ?
Hi @PamungkasJayuda
Actually there are too many containers on that docker-compose file for just a test on local machine. Try this one and let me know how the result:
version: '2'
networks:
DGRAPH_NET:
driver: bridge
services:
zero:
image: dgraph/dgraph:v21.03.0
container_name: "zero-dgraph"
volumes:
- ./dgraph_data/zero:/dgraph
ports:
- 5080:5080
- 6080:6080
restart: "no"
networks:
- DGRAPH_NET
command: dgraph zero --my=zero:5080
alpha:
image: dgraph/dgraph:v21.03.0
container_name: "alpha-dgraph"
volumes:
- ./dgraph_data/alpha:/dgraph
ports:
- 8080:8080
- 9080:9080
- 8000:8000
restart: "no"
networks:
- DGRAPH_NET
command: dgraph alpha --my=alpha:7080 --zero=zero:5080 --security whitelist=0.0.0.0/0 --graphql "debug=true;introspection=true;extensions=true;lambda-url=http://dgraph_lambda:8686/graphql-worker;"
dgraph_lambda:
image: dgraph/dgraph-lambda:latest
container_name: dgraph_lambda
ports:
- "8686:8686"
environment:
DGRAPH_URL: http://alpha:8080
volumes:
- ./dist/script.js:/app/script/script.js:ro
networks:
- DGRAPH_NET
Also add this folder to your .gitignore: dgraph_data
As far as I know, this is due to the conflict caused by multiple alpha using the same p directory. You only need to separate the data volumes of different alpha.
Here is my yaml
