Base docker image with OpenJDK 8 and MAT: `dgroup/openjdk8-mat`
8+
By default the MAT `v1.8.1.20180910` is used.
9+
10+
**Run the MAT in order to parse the heap dump**
11+
```bash
12+
docker run -it --rm -v "$PWD":/dumps -w /dumps \
13+
dgroup/mat /mat/ParseHeapDump.sh \
14+
java_pid8.hprof \
15+
org.eclipse.mat.api:suspects \
16+
org.eclipse.mat.api:overview \
17+
org.eclipse.mat.api:top_components
18+
```
19+
20+
**Run the MAT and override the default `MemoryAnalyzer.ini` settings"**
21+
1. Define your own `MemoryAnalyzer.ini`
22+
2. Pass custom settings to the docker container
23+
```bash
24+
docker run -it --rm -v "$PWD":/dumps \
25+
-v "$PWD/MemoryAnalyzer.ini":/mat/MemoryAnalyzer.ini \
26+
-w /dumps -m 5g \
27+
dgroup/mat /mat/ParseHeapDump.sh \
28+

29+
