使用docker-compose在Gitlab CI上部署失败

如何解决使用docker-compose在Gitlab CI上部署失败

我之前是通过本地计算机部署应用程序的：

// preferences[i][j] is jth preference for voter i
int preferences[MAX_VOTERS][MAX_CANDIDATES];

// Candidates have name,vote count,eliminated status
typedef struct
{
    string name;
    int votes;
    bool eliminated;
}
candidate;

// Array of candidates
candidate candidates[MAX_CANDIDATES];

// Numbers of voters and candidates
int voter_count;
int candidate_count;

// Function prototypes
bool vote(int voter,int rank,string name);


int main(int argc,string argv[])
{
 
    // Populate array of candidates
    candidate_count = argc - 1;
    
    for (int i = 0; i < candidate_count; i++)
    {
        candidates[i].name = argv[i + 1];
        candidates[i].votes = 0;
        candidates[i].eliminated = false;
    }

    voter_count = get_int("Number of voters: ");
    
    // Keep querying for votes
    for (int i = 0; i < voter_count; i++)
    {
        // Query for each rank
        for (int j = 0; j < candidate_count; j++)
        {
            string name = get_string("Rank %i: ",j + 1);

            // Record vote,unless it's invalid
            if (!vote(i,j,name))
            {
                printf("Invalid vote.\n");
                return 4;
            }
        }
        printf("\n");
    }

// Record preference if vote is valid
bool vote(int voter,string name)
{
    // TODO
    for (int i = 0; i < candidate_count; i++)
    {
        **if (strcmp(candidates[i].name,name) == 0)**
        {
        preferences[voter][rank] = i;
        return true;
        }
    }
    return false;
}

这成功，所有Dockerfiles都正确。 现在我想在GitLab CI上做同样的事情。这是我用于构建的gitlab-ci.yml文件：

> docker context create remote --docker "host=ssh://user@myhost" 
> docker --context remote ps 
> docker-compose --context remote build 
> docker-compose --context remote up -d

一切都在image: docker:19.03.12 services: - docker:dind stages: - build install_dependencies: stage: build before_script: - 'command -v ssh-agent >/dev/null || ( apt-get update -y && apt-get install openssh-client -y )' - eval $(ssh-agent -s) - echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add - - mkdir -p ~/.ssh - chmod 700 ~/.ssh - echo "StrictHostKeyChecking no " > ~/.ssh/config script: - echo "Building deploy package" - echo "$NPMRC" > ~/.npmrc - apk add --no-cache docker-compose - docker context create remote --docker "host=ssh://user@myhost" - docker --context remote ps - docker context use remote - docker-compose --context remote build - echo "Build successful" 之前，当--context arg无法识别时，我不明白为什么。

docker-compose --context remote build

解决方法

要解决此问题，docker-compose版本应至少为1.26.0。
