Apache compartilhou memória para mod_digest no contêiner Docker somente leitura

Question

Estou executando um contêiner docker usando os seguintes argumentos:

docker run -d \
    -v "$(pwd)/data/logs:/logs" \
    -v "$(pwd)/data/auth:/auth" \
    -v "/mnt/data:/data" \
    -v "$(pwd)/data/dav.config:/usr/local/apache2/conf/dav.conf" \
        --memory="2g" \
        --cpu-shares=1024 \
        --read-only="true" \
        --tmpfs /tmp --tmpfs /run \
    --restart="always" \
    --name dav \
    dav

No entanto, ao iniciar o httpd, recebo;

[Wed May 11 10:26:32.938887 2016] [auth_digest:notice] [pid 1:tid 139835054438272] AH01757: generating secret for digest authentication ...

Eu não conheço nenhuma diretiva para especificar a localização de /usr/local/apache2/logs/authdigest_shm.1 . / run e / tmp são tmpfs, o resto é somente leitura. Alguma idéia?

Tente alterar o valor da diretiva DefaultRuntimeDir

The DefaultRuntimeDir directive sets the directory in which the server will create various run-time files (shared memory, locks, etc.). If set as a relative path, the full path will be relative to ServerRoot.
