[FIXED] How to run Memgraph using the same Memgraph platform Docker image but with volume?

Issue

Is there any info on how to run Memgraph using the same Memgraph platform Docker image, but with a volume so that the data persists between restarts?

Solution

You should try running:

docker run -it -p 7687:7687 -p 3000:3000 \
-v mg_lib:/var/lib/memgraph \
-v mg_log:/var/log/memgraph \
-v mg_etc:/etc/memgraph \
memgraph/memgraph-platform

[FIXED] How to view log files while using Memgraph with Docker?

Issue

I am using Memgraph with Docker and I want to access today's log files. What is the easiest way to do that?

Solution

To view the log files you first need to enter the Docker container where Memgraph is running. Then follow these steps:

1. Execute the command docker ps to find the ID of the container, CONTAINER_ID.
2. Then, execute the command docker exec -it CONTAINER_ID bash
3. Now you can use the command cat /var/log/memgraph/memgraph_2022-03-03.log

to check today's log file.

[FIXED] How to create relationships in according to date order in Neo4j

Issue

I have many nodes and zero relationships. How can I create relationships that join the same person following date order? (the picture represents the situation I would like to obtain) See Image

Solution

If you have apoc, this is would be my approach.

MATCH (p:Person)
WITH p order by p.date
WITH p.name as personName, collect(p) as personList
WITH apoc.coll.pairsMin(personList) as pairs
UNWIND pairs as pair
WITH pair[0] as p0, pair[1] as p1
MERGE (p0)-[:SAME_PERSON]->(p1)
