发布配置分析
1.发布配置
2.controller接口
@PreAuthorize(value = "@permissionValidator.hasReleaseNamespacePermission(#appId, #namespaceName, #env)")
@PostMapping(value = "/apps/{appId}/envs/{env}/clusters/{clusterName}/namespaces/{namespaceName}/releases")
public ReleaseDTO createRelease(@PathVariable String appId,
@PathVariable String env, @PathVariable String clusterName,
@PathVariable String namespaceName, @RequestBody NamespaceReleaseModel model) {
model.setAppId(appId);
model.setEnv(env);
model.setClusterName(clusterName);
model.setNamespaceName(namespaceName);
if (model.isEmergencyPublish() && !portalConfig.isEmergencyPublishAllowed(Env.valueOf(env))) {
throw new BadRequestException(String.format("Env: %s is not supported emergency publish now", env));
}
// 3.release服务执行publish方法
ReleaseDTO createdRelease = releaseService.publish(model);
ConfigPublishEvent event = ConfigPublishEvent.instance();
event.withAppId(appId)
.withCluster(clusterName)
.withNamespace(namespaceName)
.withReleaseId(createdRelease.getId())
.setNormalPublishEvent(true)
.setEnv(Env.valueOf(env));
// 4.发布事件
publisher.publishEvent(event);
return createdRelease;
}
3.releaseService.publish方法
public ReleaseDTO publish(NamespaceReleaseModel model) {
Env env = model.getEnv();
boolean isEmergencyPublish = model.isEmergencyPublish();
String appId = model.getAppId();
String clusterName = model.getClusterName();
String namespaceName = model.getNamespaceName();
String releaseBy = StringUtils.isEmpty(model.getReleasedBy()) ?
userInfoHolder.getUser().getUserId() : model.getReleasedBy();
ReleaseDTO releaseDTO = releaseAPI.createRelease(appId, env, clusterName, namespaceName,
model.getReleaseTitle(), model.getReleaseComment(),
releaseBy, isEmergencyPublish);
Tracer.logEvent(TracerEventType.RELEASE_NAMESPACE,
String.format("%s+%s+%s+%s", appId, env, clusterName, namespaceName));
return releaseDTO;
}
3.1 releaseAPI.createRelease创建release
public ReleaseDTO createRelease(String appId, Env env, String clusterName, String namespace,
String releaseName, String releaseComment, String operator,
boolean isEmergencyPublish) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.parseMediaType(MediaType.APPLICATION_FORM_URLENCODED_VALUE + ";charset=UTF-8"));
MultiValueMap<String, String> parameters = new LinkedMultiValueMap<>();
parameters.add("name", releaseName);
parameters.add("comment", releaseComment);
parameters.add("operator", operator);
parameters.add("isEmergencyPublish", String.valueOf(isEmergencyPublish));
HttpEntity<MultiValueMap<String, String>> entity =
new HttpEntity<>(parameters, headers);
ReleaseDTO response = restTemplate.post(
env, "apps/{appId}/clusters/{clusterName}/namespaces/{namespaceName}/releases", entity,
ReleaseDTO.class, appId, clusterName, namespace);
return response;
}
发送http请求给adminService模块
3.2 adminService模块接受到请求,处理release逻辑
@Transactional
@PostMapping("/apps/{appId}/clusters/{clusterName}/namespaces/{namespaceName}/releases")
public ReleaseDTO publish(@PathVariable("appId") String appId,
@PathVariable("clusterName") String clusterName,
@PathVariable("namespaceName") String namespaceName,
@RequestParam("name") String releaseName,
@RequestParam(name = "comment", required = false) String releaseComment,
@RequestParam("operator") String operator,
@RequestParam(name = "isEmergencyPublish", defaultValue = "false") boolean isEmergencyPublish) {
Namespace namespace = namespaceService.findOne(appId, clusterName, namespaceName);
if (namespace == null) {
throw new NotFoundException(String.format("Could not find namespace for %s %s %s", appId,
clusterName, namespaceName));
}
Release release = releaseService.publish(namespace, releaseName, releaseComment, operator, isEmergencyPublish);
//send release message
Namespace parentNamespace = namespaceService.findParentNamespace(namespace);
String messageCluster;
if (parentNamespace != null) {
messageCluster = parentNamespace.getClusterName();
} else {
messageCluster = clusterName;
}
messageSender.sendMessage(ReleaseMessageKeyGenerator.generate(appId, messageCluster, namespaceName),
Topics.APOLLO_RELEASE_TOPIC);
return BeanUtils.transform(ReleaseDTO.class, release);
}
3.3 releaseService.publish
@Transactional
public Release publish(Namespace namespace, String releaseName, String releaseComment,
String operator, boolean isEmergencyPublish) {
checkLock(namespace, isEmergencyPublish, operator);
Map<String, String> operateNamespaceItems = getNamespaceItems(namespace);
Namespace parentNamespace = namespaceService.findParentNamespace(namespace);
//branch release
if (parentNamespace != null) {
return publishBranchNamespace(parentNamespace, namespace, operateNamespaceItems,
releaseName, releaseComment, operator, isEmergencyPublish);
}
Namespace childNamespace = namespaceService.findChildNamespace(namespace);
Release previousRelease = null;
if (childNamespace != null) {
previousRelease = findLatestActiveRelease(namespace);
}
//master release
Map<String, Object> operationContext = Maps.newHashMap();
operationContext.put(ReleaseOperationContext.IS_EMERGENCY_PUBLISH, isEmergencyPublish);
// 将数据写到Release表中
Release release = masterRelease(namespace, releaseName, releaseComment, operateNamespaceItems,
operator, ReleaseOperation.NORMAL_RELEASE, operationContext);
//merge to branch and auto release
if (childNamespace != null) {
mergeFromMasterAndPublishBranch(namespace, childNamespace, operateNamespaceItems,
releaseName, releaseComment, operator, previousRelease,
release, isEmergencyPublish);
}
return release;
}
看看publishBranchNamespace做了什么
@Transactional
public Release publish(Namespace namespace, String releaseName, String releaseComment,
String operator, boolean isEmergencyPublish) {
checkLock(namespace, isEmergencyPublish, operator);
Map<String, String> operateNamespaceItems = getNamespaceItems(namespace);
Namespace parentNamespace = namespaceService.findParentNamespace(namespace);
//branch release
if (parentNamespace != null) {
return publishBranchNamespace(parentNamespace, namespace, operateNamespaceItems,
releaseName, releaseComment, operator, isEmergencyPublish);
}
Namespace childNamespace = namespaceService.findChildNamespace(namespace);
Release previousRelease = null;
if (childNamespace != null) {
previousRelease = findLatestActiveRelease(namespace);
}
//master release
Map<String, Object> operationContext = Maps.newHashMap();
operationContext.put(ReleaseOperationContext.IS_EMERGENCY_PUBLISH, isEmergencyPublish);
// 发布release
Release release = masterRelease(namespace, releaseName, releaseComment, operateNamespaceItems,
operator, ReleaseOperation.NORMAL_RELEASE, operationContext);
//merge to branch and auto release
if (childNamespace != null) {
mergeFromMasterAndPublishBranch(namespace, childNamespace, operateNamespaceItems,
releaseName, releaseComment, operator, previousRelease,
release, isEmergencyPublish);
}
return release;
}
更新release的逻辑masterRelease
private Release masterRelease(Namespace namespace, String releaseName, String releaseComment,
Map<String, String> configurations, String operator,
int releaseOperation, Map<String, Object> operationContext) {
Release lastActiveRelease = findLatestActiveRelease(namespace);
long previousReleaseId = lastActiveRelease == null ? 0 : lastActiveRelease.getId();
Release release = createRelease(namespace, releaseName, releaseComment,
configurations, operator);
releaseHistoryService.createReleaseHistory(namespace.getAppId(), namespace.getClusterName(),
namespace.getNamespaceName(), namespace.getClusterName(),
release.getId(), previousReleaseId, releaseOperation,
operationContext, operator);
return release;
}
看看库里,配置已经写进去了
