In docker-solr you can simply pass these environment variables to the container. For example:
docker run -d -P -e SOLR_HEAP=800m solr
```console
$ docker run -d -P -e SOLR_HEAP=800m %%IMAGE%%
```
This works for Solr versions newer than 6.3.0. Older versions had some hardcoded defaults in `solr.in.sh`; see `docs/set-heap.sh` for how to modify that configuration.

mkdir mysolrhome
sudo chown 8983:8983 mysolrhome
docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome solr
docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome %%IMAGE%%
Solr requires a solr.xml file and configsets in the SOLR_HOME, so you must provide that ahead of time. One way of doing that is to copy the default content before running Solr:
docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome solr \
bash -c "cp -R /opt/solr/server/solr/* /opt/mysolrhome"
docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome solr
```console
$ docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome %%IMAGE%% \
bash -c "cp -R /opt/solr/server/solr/* /opt/mysolrhome"
$ docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome %%IMAGE%%
```
or, in a single command:
docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome solr \
bash -c "cp -R /opt/solr/server/solr/* /opt/mysolrhome && exec docker-entrypoint.sh solr-foreground"
```console
$ docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome %%IMAGE%% \
bash -c "cp -R /opt/solr/server/solr/* /opt/mysolrhome && exec docker-entrypoint.sh solr-foreground"
```
As an added convenience, you can pass `-e INIT_SOLR_HOME=yes` to do that automatically (if SOLR_HOME is empty):
docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome -e INIT_SOLR_HOME=yes solr
```console
$ docker run -it -v $PWD/mysolrhome:/opt/mysolrhome -e SOLR_HOME=/opt/mysolrhome -e INIT_SOLR_HOME=yes %%IMAGE%%
