Apple M1 Pro安装Azure Cosmos DB模拟器遇地址映射错误求助

修正后的操作步骤 #

• 拉取指定平台的模拟器镜像：

ipaddr="`ifconfig | grep "inet " | grep -Fv 127.0.0.1 | awk '{print $2}' | head -n 1`"
docker pull --platform linux/amd64 mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator

• 运行容器时添加--platform linux/amd64参数：

docker run \
    --platform linux/amd64 \
    --publish 8081:8081 \
    --publish 10250-10255:10250-10255 \
    --memory 3g --cpus=2.0 \
    --name=test-linux-emulator1 \
    --env AZURE_COSMOS_EMULATOR_PARTITION_COUNT=10 \
    --env AZURE_COSMOS_EMULATOR_ENABLE_DATA_PERSISTENCE=true \
    --env AZURE_COSMOS_EMULATOR_IP_ADDRESS_OVERRIDE=$ipaddr \
    --interactive \
    --tty \
    mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator

错误原因说明 #

你遇到的错误信息：

./cosmosdb-emulator: ERROR: Invalid mapping of address 0x40037db000 in reserved address space below 0x400000000000. Possible causes:

1. the process (itself, or via a wrapper) starts-up its own running environment sets the stack size limit to unlimited via syscall setrlimit(2);
2. the process (itself, or via a wrapper) adjusts its own execution domain and flag the system its legacy personality via syscall personality(2);
3. sysadmin deliberately sets the system to run on legacy VA layout mode by adjusting a sysctl knob vm.legacy_va_layout.

这是因为Apple M1 Pro采用arm64架构，而Azure Cosmos DB Linux模拟器仅提供amd64版本的二进制文件，直接运行会触发内存地址空间的映射冲突。添加--platform linux/amd64参数后，Docker会启用Rosetta 2来模拟x86_64运行环境，解决架构不兼容带来的地址映射问题。
